Great performance.

Love the performance and durability of my Michelin Pilot Sport tires. I’ve always trusted Michelins and these have exceeded my expectations so far.

Great tire

I no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

The 'Almost' Legend Continues

I first owned the Michelin Pilot Sport AS3, then my tires wore down, so went to the Michelin Pilot Sport AS3+. Now I'm currently using the Michelin Pilot Sport AS4. From my very early and initial impression (under 50 miles), these tires are the best of the group thus far. I found the AS3 and AS3+ were almost identical in tread pattern, driving, comfort with a slightly higher noise level. The AS4 feels like a significant upgrade. Firstly its an entirely new tread pattern from the past 2 models. A variation of sipe thickness and patterns. It looks like it will grip better. Briefly driving on both dry and wet roads, highway and city, it delivered nicely. It already felt great with the AS3 and AS3+, so I'd expect the same with some refinement. Personally, where I really found an improvement is the noise and comfort level. This is deemed an ultra-high performance tire. Its sporty, athletic and low profile. The handing is expected to be superb and usually the tradeoff is comfort and noise. I don't know how Michelin did it, but I've found the noise level lower and the comfort level higher. It rides much more smooth and soft with less tire noise than the AS3+. My car handles even better and I feel confident with my rear wheel ride. The only concern I have is longevity and durability. Both AS3 and AS3+ were sticky tires, so they wore down quicker and sustained nail damage. I'm expecting the same with the AS4 as I believe the tire compound is the same or similar to the previous 2 models. Plus in the end, compromises are always a result of changes. I hope I'm wrong, but time will tell. Its already a superior tire and I've had a nice history of use. Michelin, if you could make a tire with added durability (less chance of nail, staple, debris causing tire damage), you'll have a true legend! In the meantime, well done on the AS4.

HIGHLY RECOMMEND THIS TIRE!

I've installed the Pilot Sport A/S 4 on my 1995 Camaro Z28 I've own this car since new, over the 26 yrs of its life I've had several different tires. I can honestly say that this tire lives up to the Michelin standard, awesome performance in wet traction excellent overall. If you have the opportunity to purchase these tires in your size if available just do it you won't be disappointed. Only negative thing about this tire is the availability in all sizes.

Amazing tires at first AND THEN THEH WERE JUNK

Randomly worn in a section of the tire between the centre and outside edge of the tire. Only had them on my X5 for 25,000 km Always been a fan of Michelin but this is the last set I buy. I don’t even want to attempt a warranty claim because they still aren’t worth it.

Replacing Pilot HX MXM4 (comparison=Noisy,Wet=Better)

I replaced my Pilot HX MXM4 93V XL, which i had for 11 years for off winter use. New Sport All Season 4 are much better on wet surface, but the noise level when driving 50-80 km/hr is quite loud...louder than the Pilot HX MXM4's, and louder than my winter tires. So I plan to keep them on this winter and will report back how well "All Season" means.

Another Winner

I’ve previously owned the AS3 and AS3+. These new AS4 are noticeable better. It handles and grips just as good as previous models. The improvement is in the noise and comfort level. Noise being more muted, meaning in a more comfortable ride. It’s an early assessment but hope the durability and longevity will be impressive. We will see.
