How Long Do All-Terrain Tires Last? What the Warranties and Owners Say

Updated: September 19, 2026 by Emrecan Gurkan Leave a Comment

The honest answer is that nobody can tell you, and the guides quoting a range are guessing. What can be checked is what the manufacturer will pay out on, and what owners report at each stage of a tire’s life.

Across 5,950 all-terrain owner reviews, tread life complaints follow a shape that surprised us: they peak between 15,000 and 30,000 miles and fall away afterwards. All six tires we analysed show it, whether the maker backs them for 50,000 miles or 65,000. And the warranty turns out to be a poor guide to which tires disappoint: three tires share a 50,000-mile commitment and draw complaints in 1.0%, 2.2% and 12.4% of reviews.

What’s actually promised

The treadwear warranty is the only number anyone commits to in writing. It is set deliberately below what most tires achieve, which makes it a floor rather than an estimate, but it is checkable and it is the manufacturer’s own.

Read the range rather than the median. On-road all-terrains run from 40,000 to 70,000 miles, nearly a factor of two inside one category. A buyer who reads “all-terrains go about 60,000” and picks the tire at the bottom of that spread has been misled by an average rather than by the tire.

The last column matters too. Only a third of off-road all-terrain sizes carry a UTQG treadwear grade, because light-truck sizes are exempt from the rating. If you compared two tires by their treadwear numbers and then bought the LT size, the number you compared may not exist for what arrived.

The 15,000 to 30,000 mile peak

Here is where owner data says something the warranty can’t.

Complaints climb from 0.5% when the tires are new to 12.3% between 15,000 and 30,000 miles, then fall back. The ratio of praise to complaint tells the same story more sharply: 17.7 to one at the start, 1.6 to one in that middle band, and then it opens up again.

That middle band is where expectation meets evidence. Below it nobody can tell yet. In it, an owner has enough miles to judge and enough tread left to mind what they see.

The obvious explanation is that the peak tracks expectation: a set sold on 50,000 miles showing visible wear at 20,000 feels like a broken promise, while the same wear at 40,000 feels normal. If that were the whole story, tires with longer warranties should peak later.

Tread life complaints by mileage, six tires All six tires draw their heaviest tread life complaints between 15,000 and 30,000 miles, whether the manufacturer backs them for 50,000, 60,000 or 65,000.

Six tires, three warranty levels, one shared peak. The vertical reach differs between panels; the shape does not.

They don’t. All six peak in the same band, whether the warranty behind them is 50,000, 60,000 or 65,000 miles. Whatever is happening at 15,000 to 30,000 miles, it isn’t being set by the number on the box.

One limit on that reading. The mileage field isn’t filled in evenly. Every Grabber and Pirelli review carries one, and 98% of the Toyo reviews do, but only 44% of the Falken, 43% of the KO2 and 24% of the KO3. So each tire’s own curve is sound, while comparing rates between tires in a given band is not. The shape repeating across all six is the finding; the heights are not directly comparable.

Warranty doesn’t predict it

If the warranty were a good guide to how a tire wears, tires sharing one should draw similar complaints.

Tread life complaints against the warranty behind them Three tires carry a 50,000 mile warranty and draw complaints in 1.0, 2.2 and 12.4 percent of reviews.

Three tires carry the same 50,000-mile commitment and draw complaints in 1.0%, 2.2% and 12.4% of reviews. Two carry 65,000 and draw 1.0% and 3.2%. The promise and the experience are close to unrelated.

The Pirelli is the outlier and deserves a caveat: at 225 reviews it is the smallest sample here, and 28 complaints is a thin basis for a rate. It is also the only tire in the set whose complaints outnumber its praise.

Three of the six carry no UTQG grade at all, which is normal for LT-heavy all-terrains and another reason the published numbers thin out exactly where buyers want them.

Why the high-mileage numbers look good

Above 50,000 miles, two thirds of owners praise tread life outright and complaints fall to 1.4%. That is not tires improving with age.

Owners still writing at 50,000 miles are, by definition, the ones whose tires lasted. Anyone whose set wore out at 25,000 replaced it and wrote their review then, which is part of why the middle band looks as bad as it does. The apparent recovery is a change in who is left to answer.

That band also holds 140 reviews against 1,342 in the lowest one. Every rate in it rests on a handful of mentions.

Read it this way instead: if your tires reach 50,000 miles, you will probably be pleased with them. That tells you about a good outcome, not about the odds of getting one.

What actually shortens it

Nothing in the data above is something you control. These are:

  • Pressure, checked monthly and cold against the placard on the door pillar. Under-inflation loads the shoulders, over-inflation loads the centre, and either way you wear part of the tread while the rest does nothing.
  • Rotation every 5,000 miles. Lug-type patterns wear unevenly by design, and rotation is what redistributes it. Manufacturers also ask for the records when assessing a treadwear claim.
  • Alignment checked annually, and sooner after a kerb strike or suspension work. A wheel pointing slightly wrong scrubs rubber off sideways for every mile.
  • Matching the tire to the use. An off-road all-terrain driven entirely on pavement gives up warranty miles for capability it never uses.

Our guide to making tires last longer covers each of these in detail, and the wear pattern guide covers what each mistake looks like once it has been going on a while.

On-road or off-road

If you have decided on an all-terrain, this is the choice that changes the mileage:

On-road against off-road all-terrain
On-Road ATOff-Road AT
Median warranty60,000 mi55,000 mi
Weight40.0 lb48.2 lb
Tread depth12.9/32″16.0/32″
Sizes with a UTQG grade65%32%

On-road all-terrains are backed 5,000 miles further despite carrying three thirty-seconds less tread, which tells you the difference is compound and pattern rather than material. If your unpaved driving is gravel roads and forest tracks, the on-road version is the one to take.

A version of this article claimed the opposite, that off-road all-terrains last longer. The warranty data doesn’t support it.

Key takeaways

In short

  • Median treadwear warranties: on-road all-terrain 60,000 miles, off-road 55,000, rugged 50,000. Highway-terrain runs 70,000 and mud-terrain carries none at all.
  • The range inside a category matters more than the median. On-road all-terrains run from 40,000 to 70,000 miles.
  • Owner complaints peak between 15,000 and 30,000 miles, at 12.3% against 0.5% when new.
  • All six tires peak in that band whether the warranty behind them is 50,000, 60,000 or 65,000 miles.
  • Three tires share a 50,000-mile warranty and draw complaints in 1.0%, 2.2% and 12.4% of reviews. The promise doesn’t predict the experience.
  • Above 50,000 miles two thirds of owners praise tread life. That describes the survivors, not the odds.
  • Only 32% of off-road all-terrain sizes carry a UTQG treadwear grade, so the number you compared may not exist for the size you buy.

Common questions

How many miles do all-terrain tires last?

The warranties give the clearest answer available. On-road all-terrains carry a median treadwear warranty of 60,000 miles, ranging from 40,000 to 70,000. Off-road all-terrains sit at 55,000, from 50,000 to 65,000. Real mileage depends on the vehicle, the roads and the driver, and the warranty is set deliberately below what most tires achieve.

Why do complaints peak between 15,000 and 30,000 miles?

That band is where an owner has enough miles to judge and enough tread left to mind what they see. Complaints run at 12.3% there against 0.5% when the tires are new. All six tires we analysed peak in the same band regardless of their warranty, so it isn’t simply a matter of expectations being set by the number on the box.

Does a longer warranty mean the tire lasts longer?

Not reliably. Three tires in our data carry the same 50,000-mile warranty and draw tread life complaints in 1.0%, 2.2% and 12.4% of reviews. Two carry 65,000 and draw 1.0% and 3.2%. The warranty is a commercial commitment set below expected life, not a prediction of how any given owner will get on.

Do off-road all-terrains last longer than on-road ones?

No, the opposite. Off-road all-terrains carry a median treadwear warranty of 55,000 miles against 60,000 for on-road, despite having about three thirty-seconds more tread depth. An earlier version of this article said otherwise and was wrong.

Why don’t some all-terrain tires have a UTQG treadwear number?

Light-truck sizes are exempt from the rating, and they dominate the aggressive end of the range. Only 32% of off-road all-terrain sizes carry a grade, against 65% of on-road ones. Three of the six tires in our review set have no grade on any size. Check the grade for the size you are buying rather than the model.

Do all-terrain tires wear faster than highway tires?

They are backed for less. Highway-terrain tires carry a median warranty of 70,000 miles against 60,000 for on-road all-terrains and 55,000 for off-road ones. The construction explains it: an off-road all-terrain weighs about 48 lbs against a highway tire’s 37 and runs a more open pattern, which trades pavement mileage for grip on loose surfaces.

Where this comes from. Warranty figures are read from manufacturer-published warranty statements for 92 tires, and UTQG grades from spec sheets covering 3,198 sizes. Owner figures are drawn from 5,950 reviews of six all-terrain tires, classified against a fixed theme taxonomy. All six are off-road all-terrains and all are well-regarded models, so these rates describe good examples of the category rather than the category as a whole. Mileage is self-reported, appears in about half the analysed reviews, and is filled in at very different rates by tire, which is why we compare each tire’s own curve rather than the heights between them.

LT vs Passenger Tires: What Changes When Only the Casing Does

Updated: September 17, 2026 by Emrecan Gurkan Leave a Comment

Most comparisons of these two stop at “LT is stronger, passenger rides better”. That’s true and not much use, because it doesn’t tell you what you gain or what it costs.

So we found 227 cases where one manufacturer sells one tire, in one size, in both constructions. Dimensions held still, tread pattern held still, only the casing different. The light-truck version carries 21.5% more load, holds 61.6% more pressure, weighs 22.5% more and runs 22.2% more tread depth. And there is a rule about passenger tires on trucks that changes the arithmetic before you start.

The comparison that works

Averaging all passenger tires against all light-truck tires gives you a number, but a misleading one. Light-truck fitments skew toward larger sizes, so part of what you measure is the size mix rather than the construction.

Holding the size still removes that. Across 227 pairings where the same tire is offered in the same size both ways:

What changes when only the construction changes Across 227 cases where the same tire is sold in the same size in both passenger and light-truck construction, the light-truck version carries 21.5 percent more load, holds 61.6 percent more pressure, weighs 22.5 percent more and has 22.2 percent more tread depth.What changes when only the construction changes 227 cases of one tire sold in one size, both ways. Light truck against passenger. +0% +20% +40% +60% Max load +21.5% Max pressure +61.6% Tire weight +22.5% Tread depth +22.2%
Size held constant, so the only variable is the casing. Pressure moves furthest; load moves least.

Pressure moves furthest, and it is the figure that explains the ride. A casing rated to 80 psi rather than 44 is built stiff enough to contain that pressure, and it stays stiff at whatever you actually run.

Load moves least, at 21.5%. That is worth knowing if you are buying LT for capacity: the gain is real but smaller than the marketing suggests, and it comes bundled with 22.5% more weight whether you need the capacity or not.

One size, three numbers

Take the Bridgestone Dueler A/T Ascent in 275/65R18, sold in both constructions:

Bridgestone Dueler A/T Ascent, 275/65R18, both constructions
Service descriptionMax loadMax psiWeightTread depth
SL, passenger116T2,756 lbs4441 lbs12/32″
Load Range E, LT123/120S3,415 lbs8048 lbs16/32″

Swipe the table sideways to see every column.

Read the sidewalls alone and the gap is 659 lbs per tire. But if the vehicle is a light truck, the passenger tire’s rating is not what you are allowed to count on.

What the 1.1 derate does to a passenger tire on a truck A Bridgestone Dueler A/T Ascent in 275/65R18 is rated at 2,756 lbs in standard load passenger construction. Fitted to a light truck that becomes 2,505 lbs after the 1.1 derate. The light-truck version of the same size carries 3,415 lbs with no derate.The same size, three numbers Bridgestone Dueler A/T Ascent, 275/65R18, load per tire Passenger, as marked 2,756 lbs rating on the sidewall Passenger, on a truck 2,505 lbs after the 1.1 derate Light truck 3,415 lbs no derate applies
The middle bar is what the passenger tire is actually worth on a truck.

The passenger tire is worth 2,505 lbs on a truck, not 2,756. Against the LT version’s 3,415, the real gap is 910 lbs per tire, or 3,640 lbs across the set. That is a different conversation from 659.

In every one of the 227 pairings we found, the light-truck version carries more once the derate is applied. Not sometimes. Every one.

The 1.1 rule

When a passenger tire is fitted to a light truck, van or SUV, its load capacity is divided by 1.1. The tire is unchanged; the figure you are entitled to rely on is reduced.

The reason is what the ratings assume. A passenger tire is rated for passenger-car duty cycles: lighter loads, less heat, less time near the limit. Put it under a truck that tows and hauls and the same casing sees harder service, so the standard builds in a margin.

Three consequences worth carrying around:

  • A truck placard may call for a load index that looks excessive. It isn’t. It has already accounted for this.
  • Swapping LT for passenger can leave you short even when the numbers look close. A P-metric tire rated 3,000 lbs is worth 2,727 on a truck, and that difference has swallowed plenty of margin.
  • LT tires are not derated, because they were rated for this use in the first place.

Work from the placard on the door pillar and the load index it specifies. Not from what the outgoing tire happened to be, and not from the number on the sidewall taken at face value.

What the capability costs

The 227 pairings price the trade precisely, because nothing else varies.

What you gain and what you carry, same size both ways
What changesLight truck against passenger
Load capacity+21.5%
Inflation the casing holds+61.6%
Weight per tire+22.5%
Tread depth+22.2%

On the Dueler above, that is seven pounds per tire, twenty-eight across a set, all of it unsprung and rotating. Your suspension controls it over every bump and your brakes slow it at every light.

The deeper tread cuts both ways. More rubber to wear through, but taller blocks flex more under braking and steering, which is why an LT fitment often feels planted but slightly less crisp than the passenger version of the same tire.

One thing the pairings do not settle is tread life. LT sizes almost never carry a UTQG grade, so there is no published figure to compare against the passenger version. What we can say is that an LT fitment starts with more tread depth, which argues against the common claim that LT tires simply wear out sooner.

Towing

Towing is where the choice stops being about preference.

Sidewall stability matters as much as the load index. A trailer transfers weight rearward and applies side loads through every corner and crosswind. A casing that deflects under that lets the rear of the vehicle move in ways the driver has to correct. Load range C, D and E casings resist it better, and that is felt rather than measured.

Work from the placard, then check the margin. Add the tongue weight to what is already in the bed and the cab, divide across the axle, and compare against the tire’s rating with the derate applied if the tire is a passenger one. You’ll often find the margin is thinner than expected.

Load the trailer properly. Roughly 60% of cargo weight should sit forward of the trailer’s axle, with the heaviest items low and near that point. Too far back and the trailer sways; too far forward and the tongue weight overloads the rear of the tow vehicle.

The load index figures that circulate as towing minimums are rules of thumb rather than standards. The number your vehicle needs is on its placard, and it already reflects what the manufacturer expects it to carry.

Reading the markings

Three organisations set the standards, and the same tire size can be described differently depending on which one applies. This is the reference part; skip it unless a marking has confused you.

How each standard marks the same categories
TRA (United States)ETRTO (Europe)JATMA (Japan)
PassengerP before the sizeNo letterNo letter
Light truckLT before the sizeC after the sizeLT after the size
Extra loadXLXL or ReinforcedXL
Capacity expressed asLoad index, plus load range on LTLoad indexLoad index

Swipe the table sideways to see every column.

Two clarifications worth making, because a previous version of this article got them wrong.

ETRTO’s “C” is light commercial, not medium truck. A size like 195/70R15C is a van tire. Medium and heavy truck tires use a different system entirely and won’t be confused with either of these.

Load index is not a TRA alternative. All three standards use load index; it is an ISO scale. TRA additionally uses load range letters on light-truck tires, which is where C, D, E and F come from. The letters and the index describe the same capacity two ways.

The practical point survives all of this: a size with no prefix is a passenger construction even when it is fitted to a large SUV, and most modern crossover and SUV fitments are exactly that.

Which to choose

Passenger construction, if your placard calls for it, your loads are everyday loads, and your rough-road use is gravel and washboard rather than rock. You get a quieter, softer, lighter tire that costs less to run, and aggressive tread patterns are widely available in passenger sizes.

Light truck, if your placard calls for it, you tow or haul near the vehicle’s rating, you air down for trails, or you drive where a sidewall meets rock. The 21.5% capacity and the stiffer casing are doing real work in those cases.

The case that wastes money is buying LT for the look. You take the weight, the ride and the fuel consumption, and the capability sits unused. If you want the appearance, the same tread pattern is usually sold in a passenger size that will be better at everything you actually do.

For what the marking means and how to read it on a sidewall, see what LT means on a tire.

Key takeaways

In short

  • Across 227 cases of one tire in one size sold both ways, light-truck construction carries 21.5% more load, holds 61.6% more pressure, weighs 22.5% more and runs 22.2% more tread depth.
  • A passenger tire fitted to a light truck has its load capacity divided by 1.1. An LT tire does not.
  • On a Dueler A/T Ascent in 275/65R18, that turns a 659 lb sidewall gap into a 910 lb real one, or 3,640 lbs across a set.
  • In every pairing we found, the light-truck version carries more once the derate is applied.
  • Work from the placard on the door pillar, not from the outgoing tire and not from the sidewall figure taken at face value.
  • ETRTO’s “C” suffix means light commercial, not medium truck. All three standards use load index; TRA adds load range letters on top.
  • For towing, roughly 60% of cargo weight goes forward of the trailer’s axle, low and close to it.

Common questions

Are LT tires better than passenger tires?

Better at carrying load and surviving sidewall damage, worse at everything else. Across 227 same-size pairings, the light-truck version carries 21.5% more but weighs 22.5% more and runs a casing rated to hold 61.6% more pressure, which is what makes the ride firm. If your placard doesn’t call for LT and you don’t tow, haul or air down, the passenger version will be better at what you actually do.

What is the 1.1 derating rule?

When a passenger tire is fitted to a light truck, van or SUV, its load capacity is divided by 1.1. A tire rated at 2,756 lbs counts as 2,505 lbs on a truck. The tire doesn’t change; the figure you can rely on does, because passenger ratings assume passenger-car service. LT tires are not derated, since they were rated for truck use to begin with.

Can I fit passenger tires instead of the LT tires my truck came with?

Only if the load index still meets the placard requirement after the 1.1 derate. If the truck came on LT, it often came on LT because the required capacity isn’t available in a passenger size for that fitment. Check the placard on the door pillar and work from the index it specifies rather than from the outgoing tire.

Do I need LT tires for towing?

Not always, but the case for them is stronger than the load index alone suggests. A trailer applies side loads through corners and crosswinds, and a stiffer casing resists the resulting movement better. If your placard permits passenger tires and your loads are modest, they’ll do. Near the vehicle’s rating, load range C, D or E is the safer answer.

Does LT construction mean the tire wears out faster?

The spec sheets don’t support that as a rule. An LT fitment starts with 22.2% more tread depth than the passenger version of the same size, so there is more material to wear through. Whether it delivers more miles depends on compound and use, and since LT sizes almost never carry a UTQG grade, there is no published number to settle it either way.

What does the C after a European tire size mean?

Light commercial. A size written 195/70R15C is ETRTO’s way of marking a van or light-truck tire, equivalent in purpose to the LT prefix used in North America. It does not mean medium truck, which uses a different system altogether.

Where this comes from. Comparisons are drawn from 227 cases where a single manufacturer lists one tire in one size in both passenger and light-truck construction, identified across 3,182 sizes from 94 tires. Holding the size constant removes the size-mix effect that distorts broad averages between the two constructions. Figures are manufacturer-published specifications, not measurements of our own.

Are All-Terrain Tires Good in Rain? What Owners Report as They Wear

Updated: September 19, 2026 by Emrecan Gurkan Leave a Comment

Wet performance is really two questions, and separating them is most of the answer.

Wet traction is grip on a road that is merely damp, and it comes from compound and siping. Hydroplaning resistance is what stops you floating on standing water, and it comes from tread pattern and void. An all-terrain is average at the first and often good at the second, which is why owners describe them so inconsistently.

Across 5,950 all-terrain owner reviews, wet traction is praised in 12.3% and raised as a complaint in 2.9%. But that rate is not stable: complaints run at 1.3% when the tires are new and 11.0% between 30,000 and 50,000 miles. Wet grip is the thing that goes first.

Two different questions

Most guides treat wet weather as one property. It isn’t, and the two halves are governed by different parts of the tire.

The two halves of wet performance
Wet tractionHydroplaning resistance
What it isGrip on a damp roadNot floating on standing water
Comes fromCompound and sipingVoid ratio and channel geometry
All-terrains areAverage, sometimes poorOften good
WhyCompound is tuned for cut resistance, not conformityOpen patterns move water well

The compound conflict is the root of it. An all-terrain compound has to survive rock and gravel without tearing, which means resisting cuts. Wet grip needs the opposite: a compound soft enough to conform to the road’s micro-texture and displace the thin film of water on it. A tire cannot be optimised for both.

Hydroplaning is a different mechanism entirely. Water has to go somewhere, and an open lug pattern with deep voids has more somewhere than a tightly ribbed highway pattern. This is why an all-terrain can feel less sure-footed in drizzle and more sure-footed through a flooded dip on the same drive.

A previous version of this article said manufacturers use “variable pitch designs that increase the number of sipes and reduce compound stiffness.” That conflates three separate things. Variable pitch means varying the length of tread blocks around the circumference so their noise frequencies spread out rather than stacking into a tone. Siping density and compound stiffness are independent design decisions. The correction matters because it is the compound, not the pitch sequence, that sets wet grip.

What owners report

Owners raise wet traction in 15.2% of reviews, four times more often approvingly than not:

Wet traction across 5,950 all-terrain owner reviews
Share of reviews
Raised approvingly12.3%
Raised as a complaint2.9%
Praise per complaint4.3×

That is a better showing than the category’s reputation, and it comes with a caveat we should state plainly: we have no all-season reviews to compare against. These figures describe how all-terrain owners feel about their own tires, not how those tires stack up against something milder. The retailers’ scores are supposed to answer that comparison, and further down we show why they can’t.

Read this with the sample in mind. The six tires behind these figures are among the better-regarded all-terrains available. A budget tire with an aggressive pattern is a different proposition and isn’t represented here.

The complaint that arrives with wear

The headline rate hides the most useful thing in the data.

Wet traction mentions by mileage Wet traction complaints run at 1.3 percent of reviews below 5,000 miles and 11.0 percent between 30,000 and 50,000, an eightfold increase.

The steepest curve in the review set. Praise stays flat while complaints multiply eightfold.

Wet complaints run at 1.3% below 5,000 miles and 11.0% between 30,000 and 50,000. That is an eightfold increase, and it is the steepest curve of any theme we track, steeper than noise and steeper than tread life.

The mechanism is direct. Hydroplaning resistance depends on how much water the grooves can move, and groove depth is exactly what wear takes away. A tire that starts with 16/32″ of tread and reaches the legal limit at 2/32″ has lost seven eighths of its water capacity while still being legal to drive.

Praise, meanwhile, stays roughly flat across every band. Owners who are happy stay happy; the ones who aren’t are discovering something that changed underneath them.

The practical version: the wet performance you evaluate in the first month is not the wet performance you will have at 35,000 miles. If you drive in rain regularly, tread depth is worth watching long before the tire is legally worn out. Four thirty-seconds is the usual threshold for wet driving, against the two that the law requires.

Which all-terrain

As with every other dimension we have measured, the model matters more than the category:

Praise runs from 8.2% to 18.2%, more than double at one end of the list than the other. Complaint rates are tighter, from 2.4% to 4.3%, which suggests the difference is more about how often a tire impresses than how often it disappoints.

Why the scores can’t help here

If you want to compare an all-terrain against an all-season for wet weather, the obvious source is the retailers’ wet score. It does not work, and the reason is instructive.

Wet scores against tread depth by category Published wet scores run from 4.20 to 4.50 across categories whose tread depth runs from 10.1 to 20 thirty-seconds of an inch. Mud-terrain tires carry twice the tread depth of touring tires and score a tenth of a point lower for wet.The wet column barely moves Median TireRack wet score, with the tread depth behind it 4.0 4.2 4.4 4.6 TREAD DEPTH Highway-Terrain 4.5 12.0/32″ Touring 4.4 10.1/32″ Off-Road AT 4.4 16.0/32″ Mud-Terrain 4.3 20.0/32″ On-Road AT 4.3 12.9/32″ Rugged AT 4.2 17.6/32″ Commercial AT 4.2 18.0/32″
Twice the tread depth, a tenth of a point apart.

Wet scores run from 4.20 to 4.50 across categories whose tread depth runs from 10.1/32″ to 20/32″. A mud-terrain carries twice the tread of a touring tire, is built on a completely different compound, and scores a tenth of a point lower.

Nobody believes those tires perform within a tenth of each other in the rain. What the scores record is whether an owner felt they got what they expected, and a mud-terrain buyer is not expecting touring-tire wet grip. Satisfaction and performance come apart hardest exactly where the expectations differ most.

So the wet column is the one place in these ratings we would tell you to ignore outright. Use it to compare tires inside one category, where buyers want similar things, and not at all across categories.
