Every guide to these categories tells you the same thing: highway tires are quiet and last, all-terrains compromise, mud-terrains grip and wear out. All of that is roughly true and none of it tells you how much.
So we measured. Across 95 tires, a mud-terrain weighs 67 lbs against a touring tire’s 30.5 and carries twice the tread depth. Warranties fall from 70,000 miles to nothing at all. And the retailers score every one of those categories between 4.8 and 4.9 out of five for treadwear, which tells you what a star rating is worth.
The ladder, in numbers
Seven categories, arranged from road-biased to off-road-biased. Every column below moves in the same direction, which is the first useful thing to know: these are not seven unrelated products but points along one trade.
| Category | Tires | Weight | Tread depth | Max load | Warranty | 3PMSF |
|---|---|---|---|---|---|---|
| Touring | 7 | 30.5 lb | 10.1/32″ | 2,039 | 65,000 | 14% |
| Highway-Terrain | 25 | 37.0 lb | 12.0/32″ | 2,469 | 70,000 | 16% |
| On-Road AT | 25 | 40.0 lb | 12.9/32″ | 2,607 | 60,000 | 76% |
| Off-Road AT | 17 | 48.2 lb | 16.0/32″ | 2,853 | 55,000 | 94% |
| Commercial AT | 3 | 48.0 lb | 18.0/32″ | 3,195 | 50,000 | 33% |
| Rugged AT | 8 | 61.0 lb | 17.6/32″ | 3,305 | 50,000 | 38% |
| Mud-Terrain | 7 | 67.0 lb | 20.0/32″ | 3,195 | none | 0% |
Swipe the table sideways to see every column.
Two things jump out of that table before you read any further. The winter column peaks in the middle rather than at either end. And the warranty column ends in a word rather than a number.
What actually changes
A mud-terrain tire weighs 2.2 times what a touring tire does and carries twice the tread depth. Those two numbers explain most of what follows.
The weight is unsprung and rotating, which is the worst kind to add. Your suspension controls it over every bump, your brakes slow it at every light, and your engine accelerates it from every stop. Thirty-six extra pounds across a set is not a rounding error.
The tread depth is where the grip comes from and also where the noise and the vagueness come from. Taller blocks have more edges to bite with off-road, more void to clear mud from, and more flex under braking and steering on pavement. There is no way to have one without the others.
Load capacity rises alongside, from 2,039 lbs to around 3,200. That is the part buyers usually want, and it arrives bundled with the rest whether they want that or not.
What they promise on wear
The warranty ladder runs cleanly downward, and then stops:
| Category | Median warranty | Range | With no cover | Median UTQG | Sizes graded |
|---|---|---|---|---|---|
| Highway-Terrain | 70,000 | 50,000–75,000 | 2 | 680 | 75% |
| Touring | 65,000 | 55,000–70,000 | 0 | 640 | 100% |
| On-Road AT | 60,000 | 40,000–70,000 | 2 | 610 | 65% |
| Off-Road AT | 55,000 | 50,000–65,000 | 0 | 600 | 32% |
| Rugged AT | 50,000 | 45,000–60,000 | 1 | 540 | 22% |
| Commercial AT | 50,000 | 50,000 only | 2 | 320 | 10% |
| Mud-Terrain | none | — | 7 of 7 | — | 0% |
Swipe the table sideways to see every column.
Two claims this article used to make don’t survive the table.
“Off-road all-terrains last longer than on-road all-terrains.” They don’t. Off-road ATs are backed to a median of 55,000 miles against 60,000 for on-road. The direction is the opposite of what we wrote.
“Commercial all-terrains have a longer lifespan.” They carry the lowest warranty of any category that carries one, at 50,000 miles, and the lowest UTQG grade at 320. Two of the three have no mileage cover at all.
Winter certification
The three-peak mountain snowflake certifies acceleration traction on packed snow. Its distribution across these categories is not what intuition suggests:
| Category | Tires | Claim 3PMSF |
|---|---|---|
| Off-Road AT | 17 | 94% |
| On-Road AT | 25 | 76% |
| Rugged AT | 8 | 38% |
| Commercial AT | 3 | 33% |
| Highway-Terrain | 25 | 16% |
| Touring | 7 | 14% |
| Mud-Terrain | 7 | 0% |
Certification peaks in the middle of the ladder and falls away at both ends. Highway tires lack the biting edges and run compounds tuned for wear. Mud-terrains fail for the opposite reason: the test rewards packing snow into the tread, because snow grips snow better than rubber does, and a mud-terrain pattern is built to eject exactly that.
So the most aggressive-looking tire in the range is the one least likely to be certified for snow. Our guide to what the snowflake certifies goes into what that does and doesn’t mean once you have it.
Twelve tires, one vehicle
Everything above compares specifications. This compares performance, with the vehicle, surface, drivers and date held constant.
The ordering is what you would expect. On-road all-terrains took first, second and fourth. Off-road all-terrains landed fifth, seventh, ninth and tenth. Rugged terrains sixth and eleventh.
Across every test where two categories met, the more road-biased one scored higher, without exception. On-road ATs beat off-road ATs in both tests where they appeared together, and off-road ATs beat rugged terrains in both. The ladder holds.
The gap inside a category
Here is the part the category framework hides.
In that same test, the five on-road all-terrains scored from 6.95 down to 5.46, a spread of 1.49 points. The gap between the on-road all-terrain median and the off-road all-terrain median was 0.54.
The same pattern shows in the October test: rugged terrains ran from 6.45 to 5.38, while the gap between the off-road and rugged medians was 0.17.
Which category you pick matters less than which tire you pick within it. A good off-road all-terrain outscores a poor on-road one, comfortably and repeatedly. The category tells you roughly where a tire sits; it does not tell you whether it is a good example of its type.
That is worth holding onto when a guide, including this one, hands you a table of categories. The table is a starting filter, not an answer.
What the star ratings miss
The retailers publish a score for every dimension of every tire. Across this range they do separate the categories, and in the order you would expect:
| Category | Dry | Wet | Winter | Comfort | Noise | Treadwear |
|---|---|---|---|---|---|---|
| Touring | 4.60 | 4.40 | 3.70 | 4.40 | 4.25 | 4.40 |
| Highway-Terrain | 4.60 | 4.50 | 3.90 | 4.50 | 4.50 | 4.40 |
| On-Road AT | 4.50 | 4.30 | 4.00 | 4.30 | 4.30 | 4.30 |
| Off-Road AT | 4.60 | 4.40 | 4.30 | 4.30 | 4.20 | 4.35 |
| Rugged AT | 4.60 | 4.20 | 4.00 | 4.20 | 4.10 | 4.30 |
| Commercial AT | 4.30 | 4.20 | 4.30 | 3.90 | 3.70 | 4.00 |
| Mud-Terrain | 4.50 | 4.30 | 4.20 | 4.00 | 3.80 | 4.20 |
Swipe the table sideways to see every column.
Comfort and noise both fall as tires get more aggressive, by 0.5 and 0.7 points from the top of the range to the bottom. Winter rises, from 3.70 for touring tires to 4.30 for off-road all-terrains, which agrees with the certification data above. Those columns are doing real work.
Treadwear is where it breaks down.
| Category | Treadwear score | Actual warranty |
|---|---|---|
| Highway-Terrain | 4.40 | 70,000 mi |
| Off-Road AT | 4.35 | 55,000 mi |
| Rugged AT | 4.30 | 50,000 mi |
| Mud-Terrain | 4.20 | none |
A tire backed for 70,000 miles scores 4.40. A tire its maker will not put any mileage figure on at all scores 4.20. Two tenths of a point separates a written commitment from the absence of one.
The reason isn’t that the scores are wrong. It’s that they are measuring something else: whether an owner felt they got what they expected. A mud-terrain buyer does not expect 70,000 miles, so getting 35,000 registers as satisfactory. The score is honest about satisfaction and silent about durability, and those are different questions.
The same caution applies to the wet column, which is nearly flat at 4.20 to 4.50 across categories that differ enormously in tread depth and void. Nobody believes a mud-terrain grips wet pavement within a tenth of a point of a highway tire. What the numbers record is that its buyers were not expecting it to.
Read these scores against other tires in the same category, where expectations are comparable. Reading them across categories is where they mislead.
The categories one by one
Touring
The lightest and shallowest in the range at 30.5 lbs and 10.1/32″. Every size carries a UTQG grade, warranties run 55,000 to 70,000, and only one of seven claims the snowflake. Built for crossovers and unibody SUVs, where the vehicle never asks for load capacity and the driver notices ride quality daily.
Highway-Terrain
The longest-warrantied category at a median of 70,000 miles, with a range from 50,000 to 75,000. Heavier than touring at 37 lbs and rated for more load, because these go on body-on-frame trucks and full-size SUVs. Only 16% carry the snowflake, so if your winter involves snow rather than just cold, check the specific tire rather than the category.
On-Road All-Terrain
The compromise that works for most people. 40 lbs, 12.9/32″, 60,000-mile median warranty, and 76% carry the snowflake. In the one test where five of them ran against the more aggressive categories, they took first, second and fourth. Also the category with the widest warranty range, 40,000 to 70,000, so the name tells you less than the specific tire does.
Off-Road All-Terrain
Where the trade starts to bite: 48 lbs, 16/32″ of tread, and a 55,000-mile median warranty, less than the on-road category above it. 94% carry the snowflake, the highest of any category. Only 32% of sizes carry a UTQG grade, because LT construction dominates here.
Rugged Terrain
61 lbs, the second-heaviest, with 17.6/32″ of tread and the highest load rating in the range at 3,305 lbs. Warranties drop to 50,000 with one tire carrying none. 38% claim the snowflake, so the old line that rugged terrains generally lack it is fair. What isn’t fair is the claim that they are relatively quiet: their noise score of 4.10 sits below the off-road all-terrain 4.20 and well below the highway-terrain 4.50.
Commercial All-Terrain
A small and unusual category, three tires in our data. Deep tread at 18/32″ and high load at 3,195 lbs, but the lowest warranty of anything that carries one and the lowest UTQG grade at 320. Two of the three carry no mileage cover. Built for work vehicles on job sites, where puncture resistance matters more than mileage.
Mud-Terrain
The end of the ladder: 67 lbs, 20/32″ of tread, no mileage warranty on any of the seven, no UTQG grade on any of the 219 sizes, and no snowflake anywhere. Everything about this category says the same thing, which is that it exists for one job and its makers decline to promise anything about the rest.
Choosing
Work down rather than up. Start from what your vehicle and your week actually require, then add capability only where something forces you to:
- Your placard first. Load index and construction are settled before taste enters into it.
- How often does the surface change? Gravel roads and forest tracks are on-road all-terrain territory. Rock, ruts and aired-down running are not.
- What does winter mean where you live? If it means snow, the snowflake matters and highway tires mostly lack it. If it means ice, no tire in this range replaces a winter tire.
- What are you giving up daily for what you use rarely? Thirty-six pounds a set and ten thousand miles of warranty is a real price for capability that sees use twice a year.
- Then compare within the category, not across it. The spread inside a category is wider than the gap between categories.
Key takeaways
In short
- A mud-terrain tire weighs 67 lbs against a touring tire’s 30.5, and carries twice the tread depth.
- Warranties fall from 70,000 miles for highway-terrain to nothing at all for mud-terrain, where all seven carry no mileage cover.
- Off-road all-terrains do not last longer than on-road ones: 55,000 against 60,000 miles.
- Commercial all-terrains carry the lowest warranty and the lowest UTQG grade of any category.
- Snowflake certification peaks in the middle at 94% of off-road all-terrains, and reaches 0% for mud-terrains.
- In a twelve-tire test on one vehicle, the spread inside the on-road all-terrain category was 1.49 points; the gap between category medians was 0.54.
- Retailer treadwear scores run 4.40 for a category backed to 70,000 miles and 4.20 for one with no mileage warranty at all. Comfort and noise scores do separate the categories; treadwear doesn’t.
Common questions
What’s the real difference between highway, all-terrain and mud-terrain tires?
Weight and tread depth, mostly, and everything follows from those. A mud-terrain weighs 67 lbs against a highway tire’s 37 and carries 20/32″ of tread against 12/32″. That buys grip on loose surfaces and costs ride quality, noise, fuel and warranty. Warranties fall from a median of 70,000 miles for highway-terrain to none at all for mud-terrain.
Do off-road all-terrain tires 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 all-terrains. An earlier version of this article claimed otherwise and was wrong.
Why don’t mud-terrain tires have a mileage warranty?
Their life varies too much with use to guarantee. All seven mud-terrains in our data carry a treadwear warranty with no mileage attached, and none of the 219 mud-terrain sizes carries a UTQG treadwear grade either. Any specific mileage figure you see quoted for one did not come from the manufacturer.
Are all-terrain tires good in snow?
Most are certified for it. 94% of off-road all-terrains and 76% of on-road all-terrains carry the three-peak mountain snowflake, against 16% of highway-terrains and none of the mud-terrains. The symbol certifies acceleration traction on packed snow only, so it says nothing about ice, and no all-terrain replaces a winter tire where ice is the problem.
Is a rugged-terrain tire quieter than an all-terrain?
Not according to the ratings. Rugged terrains score 4.30 for noise against 4.35 for off-road all-terrains, so slightly worse rather than better. They are also 13 lbs heavier on average, and mass transmits road texture into the cabin independently of tread pattern.
Should I choose by category or by individual tire?
Use the category as a filter, then compare within it. In a twelve-tire test on one vehicle, the five on-road all-terrains spread 1.49 points while the gap between the on-road and off-road category medians was 0.54. A good example of a more aggressive category regularly outscores a poor example of a milder one.
Where this comes from. Construction figures are medians across manufacturer spec sheets covering 3,198 sizes from 95 tires. Warranty and UTQG figures come from published warranty statements and spec sheets. Snowflake certification is detected from manufacturers’ own descriptions, so a tire carrying the symbol without mentioning it would be counted as uncertified. Test scores come from published results and are compared only within a single test, since vehicle, surface and date differ between them. All the tests we hold were scored on pavement. Categories with three or fewer tires rest on very small samples and are marked as such. Owner review data is not yet broken out by category; we’ll add it here when it is.
