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.

I've had a few good tires in my life, but nothing like the wow factor of this new design. The wet traction is outstanding. This tire inspires a lot of confidence. So much technology with the tread design and the compound. I'm not looking forward to the snow, but with this tire I feel that it will not be a problem. This might be the perfect tire for the Pacific Northwest. I live in Vancouver BC and we get lots of rain. My old set of P Zeros feel like crap in comparison to the Michelin AS4. My Mustang loves these tires !!! :)

I bought mine for an Audi A6 3.0T Quattro when the car had 52k miles on it. Absolutely loved how they handle on wet and dry roads. However, super disappointed with tread life. I have 81K on them now and one tire is almost completely bald, and the others might have 2/3K left until they look similar. Not an alignment issue either as they were rotated and tread is worn evenly. We swear by Michelin tires, and love the Defenders on our Yukon, which is why I’m being fair with 4 stars. But I will probably consider something else to replace these Pilots for this particular vehicle.

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.

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.

My car seems to ride a little harder, than before. I removed Continental tires from my Mercedes C300.The ride sounds loud,if that makes since. But for the price I guess that was pretty good. Not to mention the warranty that came with them. Life of the tire balancing, rotation, etc, etc.

Excellent traction, handling & performance! Noise is acceptable; only one negative: NOT getting 45,000 as estimateddurability. Wheels aligned at purchase. However, durability is an issue. ONLY 11012 miles on 4 tires--and will have to purchase new tires in 6 months! Great warranty on tires damaged by nails.

I just purchased a set of Michelin Pilot Sport 4 for a 2020 WRX Sport-tech RS. Replacement for the OEM Dunlop SP Sport Maxx RT which wore out prematurely (~30 000 km). I immediately noticed much less road noise with the Pilot Sport 4 compared to the Dunlop tirs. My wife even commented: "It's quiet now, like a normal car". So far noticeably more comfortable on rough roads with good handling. Hopefully, the Michelin tires are more durable. Will see how

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.

Just had these tires installed on my Kona Urban Edition. (Pilot Sport AS4) I am very pleased with the sporty look of these on my car. Also it was raining pretty hard while driving with these and found them very responsive with very good braking as well. (While following recommended speed limits) Another plus is that they are quiet! Very smooth ride too. Both on Highway and town driving. I feel they grip the road exceptionally well. They should serve me well for my driving needs. Highly recommend.
