Bought these tires for the wife's car, she seems happy. Car had from the factory "run flat" tires on it. These are not run flats(thankfully). Car rides much nicer. She is happy. Draw back is now I have to get an extra wheel for a spare, which I would prefer anyway, remember tires do come apart sometimes, run flat or regular tire.

What a difference in the performance from my OEM tires. I put these on my Audi SQ5 replacing the "performance" tires that I had on there that only got about 10,000 miles. I had these new tires for about two months now and the performance of these tires blows away my other tires. It was very difficult to find a 21" all season performance tire at a affordable price. Today My wife drove the car on the freeway in a down pour and she felt very comfortable driving as it proved to be a tire that made the car very stable and responsive. It made this purchase worth every penny. So if you have a vehicle with a performance 21" tire I highly recommend the Michelin Pilot. Thank you Michelin for an awesome tire.

I bought this set of tire about a year ago and can say they are the best All Season Sport tire on the market. The tires were purchased for my 2021 Roush Stage 3 Mustang which has 760 HP, 670 Ft. Lbs. TQ. The car can push any tire to its limits but the Pilot Sport A/S 4 handles the power in a very linear fashion. Yes, a Pilot Summer only tire would stick to the road better if I ran it on the track but that is not going to happen. For my very spirited driving I have found the Pilot A/S Sport 4 tire handle the twisting back mountain roads with ease. I highly recommend these tires for anyone who wants the best of All Season and Track only tires in one set of tires. Unless you plan on putting your car on a drag strip or the big oval this is all the tire you will ever need.

These tires lasted me 57,000 miles on my Tesla Model 3 RWD. Would probably last another 2500 miles but changing before rainy season in california. Tires are very grippy in rain and dry, but the noise and drone of tires is a bit excessive. Overall I love the performance, safety and longevity of the tire so decided to get a second pair.

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.

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.

I drive a RWD P85+ Tesla Model S, which is both heavy and up until last winter had staggered 21” wheels. I was used to buying a new set of Pilot Sport 4S for the rear every 10-12k miles, which is to be expected, but not welcomed on that setup. I switch to 20” square rims front and aft, and also switched to Pilot Sport AS 4's ,245/45/ZR20 99Y, and couldn't be happier. Now that I can rotate tires life if grand. I'm used to extremely irregular wear and regular pinch flats, but I've got things nailed down now. Tire wear with theses tire is even, traction is more than adequate and tire noise is drastically reduced.

I bought these today 1/25/21 at 12pm and drove for approximately 100 miles and boy let me tell you. I came from Pirelli scorpion run flat tires and it is a night and day difference. These Michelin’s are on the money. What a smooth floaty drive on my 17’ X5 MSPORT. These tires are very sticky as I hear them when I roll down the windows. Very responsive steering improvement from runflats. These tires are everything. I feel much safer having my family in the car. Thank you Michelin.

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.

After 22 months & 17k miles: Exceptional high speed handling and control. Extraordinary protection from hydroplaning. Excellent snow and ice performance for a non-snow/ice tire. It takes real work to break traction, even with traction-control disabled during wet weather. Do NOT confuse the Pilot Sport AS4 (High-Performance All-Season M+S rated - 45k warranty) for the Pilot Sport 4S (HP soft compound Summer "only" tire - 30k). Several of the negative reviews on here clearly suffer this confusion over the 4S.
