As a former Bridgestone engineer, from my standpoint, Laufenn S Fit AS is a unique performance tire if you’re focused on handling and fuel efficiency. Since Laufenn focuses on fuel efficiency in this tire, they use fewer sipes on this tire. Hence, its wet and winter performances are poor below 7 Celcius degrees (at or below 40º F). However, if you’re living in a warm region, these tires are a great option for you. Laufenn S Fit AS lasts long. Yet, due to its variable shoulder block design, it’s slightly noisy at low speeds but deaf at high speeds.

Dry Traction
First of all, I would like to share my opinion about UHP tires. They’re just all-season tires that have stronger sidewalls. That’s it. In my point of view, the all-season tire concept is totally the opposite of the performance tire concept. For sure, brands like Michelin, Bridgestone, and Continental can optimize these tires perfectly. Yet, these are just all-season tires that offer higher speed ratings and cornering stability. That’s it.
Why I’m talking about them in this section? Because if your expectations are racing or great handling on high velocity, you’re in the wrong place. You need a slick summer performance tire.
On the other hand, besides the longevity, if you just like the appearance and your expectations are just safety while driving slightly aggressively, let’s move on!
Laufen S Fit AS’s compound is labeled with A-rating regarding traction. So, its traction capability is great.
Regarding dry traction, putting as much rubber on the ground works best. Besides that, compound stiffness is the game-changer. Luckily, Laufen S Fit AS has a soft compound like every other ultra-high-performance tire(500 UTQG rating).
Unlike most UHP tires, Laufen S Fit AS doesn’t have a blocky pattern which increases the rubber on the ground. For this reason, I can confidently say that even if you’re changing from all-season tires, you’ll not notice any decrease in dry traction.
Laufen S Fit AS offers great dry traction.
Handling
The handling capability of UHP all-season tires is crucial.
The handling capability of the tires can be evaluated under two different features.
The first one is responsiveness, also known as steering response.
The second one is cornering stability. This kinda shows your tire’s ability to stay stable under high speeds.
Let’s evaluate them one by one.
Steering Response
Steering response is related to compound stiffness and tread design.
Well, I have to admit that, UHP all-season tires have an advantage out here. All-season performance tires have a stiff compound for performance tires. Hence, these tires flex less and provide a quicker steering response.
In this case, the real game changer is the center rib design. Manufacturers mostly keep center ribs robust and solid. Just like Laufen S Fit AS has.
Moreover, Laufen S Fit AS’s ribs are connected to the tire bars that reduce the flex and accelerating the steering response. Moreover, Laufen S Fit AS’s tread depth is lower than the competition. It’s a bad omen for tread life but increases the responsiveness significantly, especially for the tires that have a fluffy compound.
Even though these are enough for a decent steering response, responsiveness is also highly related to cornering stability.
I can confidently say that Laufen S Fit AS offers a trustworthy steering response, though, I’ll share a couple of extra pieces of information in the below section.
Cornering Stability
Cornering stability is mostly related to the inner structure. Hence, most performance tires have a decent record.
In that case, two steel belt construction works best. For this reason, it has a common use. Well, Laufenn uses the same design for S Fit AS also. However, the X factor out here is different.
Laufen uses a jointless nylon cap that fully covers the steel belts and meets with a high-hardness bead filler that reduces the flex and offers better cornering stability.
Laufen S Fit AS offers reliable cornering stability. That feature makes it a good option for SUVs and CUVs that puts performance over the tread life.
Wet Performance
This section is actually the reason why I don’t like all-season performance tires.
The wet performance requires a fluffy compound or a notched rubber. Though, compounds do most of the work.
In fact, summer tires work better on wet because of this reason. The fluffy compound offers a better grip on wet.
The above reasons are important for wet traction. Yet, hydroplaning resistance is another feature that is highly crucial for high-speed driving.
Let’s move on and talk about them one by one.
Wet Traction
Wet traction is related the compound stiffness and there’s a solid way to understand it.
Checking UTQH rating. Laufenn S Fit AS has a 500 AA UTQG rating. The first A out here stands for the wet traction.
In this case, what you have to pay attention to is in which conditions the above sentence is valid. Above 7 Celcius (44.6° Fahrenheit) degrees.
If the tire doesn’t have 3PMSF, its compound sometimes can lose grip capability. Well, LAufenn S Fit AS doesn’t have.
In order to avoid this, manufacturers use highly notched rubber on performance all-season tires. However, Laufen S Fit AS isn’t one of these tires.
Laufenn S Fit AS has big shoulder blocks and a continuous rib design that increase the comfort level but decreases the biting edge intensity, hence, slippery ground grip.
Laufen S Fit AS offers decent wet traction for warm regions. However, under 7 Celcius degrees, it loses grip capability significantly.
Hydroplaning Resistance
Hydroplaning resistance is basically water throwing-out capability of the tire.
If the water stays inside the tread, the tire tends to lose connection with the ground. This doesn’t happen on a smooth road. Yet, you probably feel the flotation feeling while going through the puddles.
Performance tires have wider tread patterns. For this reason, they tend to hydroplane.
In order to avoid it, there are two different methods.
The first one is using circumferential grooves. Laufen S Fit AS has a 3-rib design, for this reason, it has 4 circumferential grooves which is an efficient number.
The second one is open shoulder blocks. Right here, manufacturers need to decide between riding comfort and hydroplaning resistance.
The big shoulder blocks and fewer open slot is disadvantage out here. Check the tread closely, one shoulder is supported with a small rib that increases the handling but decreases the hydroplaning resistance.
Laufen S Fit AS offers average hydroplaning. It handles the lower velocity but high-speed hydroplaning needs a better shoulder design.
Longevity
Laufenn S Fit AS’s tread design aims the longevity.
If you compare this tire with its competitors, you can clearly see that this one has a softer design.
It doesn’t have a blocky pattern like its competitors and its sipe and notches density is actually low.
These features decrease its slippery ground grip capability but decrease its rolling resistance significantly.
Since the tire has a low density of sipes, it offers satisfying tread life. However, its compound is slightly softer than the competition (500UTQG, premium brands use 560-600 for this segment). Well, in fact, that’s why this tire still can offer slippery ground performance.
Besides all of these, Laufenn is aware that even wearing is the key to long-lasting rubber. So, they use tie bars to decrease flexing between the ribs. For this reason, Laufen S Fit AS tends to wear evenly.
If you’re looking for a long-lasting rubber, Laufenn S Fit AS is a great option for you.
Getting maximum wear life from a tire is related to you as well as your tire,
If you’d like to learn how to get maximum tread life:
Warranty
- Laufenn offers 5 years and 45,000 miles treadwear warranty for this product
- You have a 30 days trial option
- If you don’t like it, you can replace it with a set of Laufenn or Hankook tires
Here is the detailed warranty document for you,

Winter Performance
Winter performance of performance tires is questionable.
Performance tires aren’t able to use 3PMSF compound because of wearing issues.
3PMSF compounds are fluffy and don’t lose their elasticity in freezing temperatures. However, they melt down on high-speed usage. Especially in warm weather.
Regarding Laufen S Fit AS, things are worse.
The premium brands in this category prefer a more aggressive and blocky design to improve grip capability. Unfortunately, Laufen S Fit AS’s design is insufficient for winter performance.
I don’t recommend this tire for winter usage.
Riding Comfort
It seems like riding comfort is the priority of Laufen S Fit AS.
Unlike its successors, Laufen S Fit AS has a less blocky compound.
However, the inner structure does most of the work in this case.
So, riding comfort is related to uniformity. For this reason, performance tires generally fail on it. These tires have a fluffy compound but they have durable and solid shoulder blocks and sidewalls.
Things are quite the same for Laufen S Fit AS, however, its shoulder block design creates a difference in this case.
Laufenn defines 5 different stiffness levels for Laufenn S Fit AS’s shoulder blocks. These blocks meet with the surface respectively. However, even though you drive at a constant speed, these blocks hit the surface with a different force because the tire is a circle and it has harmonic movements. So, optimizing the stiffness level of these blocks is a quiet smart move to make and it also decreases the noise level.
Due to its specific shoulder block design, Laufenn S Fit AS offers an exceedingly smooth drive.
Road Noise
If you’re looking for high-performance all-season tires, especially affordable ones, you probably don’t care about the road noise that much.
These tires are built to perform under high lateral forces. Hence, these tires have a strong sidewall and robust shoulder blocks.
So, before saying anything, I can confidently say that this one gonna be slightly louder than your all-season tire for sure.
First of all, the issue is manufacturer needs deep and wide notches to increase the traction capability of these tires. These deep and wide notches on the center section create some noise for sure.
However, the real issue is the wavy circumferential outer shoulder groove. The noise of all-season tires is mostly created by the airflow. So, these wavy sections increase the hydroplaning but also increase the noise level.
So, Laufenn uses a semi-rib near the wavy shoulder blocks. This semi-rib blocks the airflow and decreases the noise level. Yet, this can just slightly decrease it, can’t completely fix it.
If you’re buying this tire for high-speed driving, then it’s an extremely quiet tire, yet, I think that it’s noisier than all-season tires at lower speeds.
Fuel Efficiency
Laufenn S Fit AS is one of the lightest ultra-high performance all-season tires in the market which makes it a good option for a better MPG.
Besides that, just like I’ve mentioned before, Laufenn S Fit AS’s design isn’t blocky as its competitors. It might be bad for traction-related features but it’s great for smooth and quiet driving and fuel efficiency.
If fuel efficiency is your priority, Laufenn S Fit AS is one of the best ones you can get!
