Mounted these tires on my Mazda 3 GT in May of 2021. Got about 7,000 on them now and I have been well pleased with their performance. Seems I chicken out before these things reach their limit as I have yet to have them squawk back to me during sever cornering, severe stopping, severe acceleration, ( well it's a four banger should just call it snappy acceleration).The performance is just outstanding in all conditions. I would like to find some fault with them but I have nothing to complain about. Good job big ol squeezy Michelin Man.

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.

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.

Replaced OEM 2020 Mustang with Michelin Pilot Sports all season. Absolutely, love them. A quiet high performance tire that grips the road on tight curves. You can feel the traction grip the road when you takeoff. This tire is also a smooth riding tire. A notch above the Eagle F1 and Continental DWS 06 plus.

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.

Tire has amazing qualities in which i love. Tread will not keep up the 45,000 miles in which is stated. 255/40/ZR21 & 265/40/ZR21 Are the tire sizes i own. I can not purchase Hazard Insurance due to size of tire, thankfully i have not had an instance which requires it but its good to have. Please create a tire for winter for these sizes. Much appreciated!

I am 60 yrs old and my wife is 67 yrs old. We bought a set of these tires 2 yrs ago for our Audi A7 and have 30,000 miles on them. They are already worn out to the red replacement stage. These tires are such a disappointment. I have always tried to buy Michelin but will be looking elsewhere now.

Just purchased one 275/40/18 tire for Mercedes Wow these tires are light weight ,softer rubber texture Very limited amount of road noise. These tires somehow makes me feel more secure driving in the rain because it Has like minimal slipping It gives you an straight ahead planted feeling while driving in the rain even above highway speeds (You generally shouldn’t do ) On dry roads it creates perfect grip , turns where I point the steering wheel My car is a 5,145 pound Mercedes s55 and the tires makes me feel confident and more in control. But like they say on reading rainbow ,don’t take my word for it, buy the tires for yourself ! And you’ll see what I’m talking about first hand

I bought the Michelin Pilot Sport All Season 4 (ZR rated) for my Lexus LS. These tires are SO NOISY!! They are also hard and you feel the shock from rough roads. They are much noisier than my old Michelin tires. However, they are much better than the Michelin Primacy mxm4 A/s which I swapped for the Pilot Sport. AVOID, AVOID, AVOID both the Primacy mxm4 and Pilot Sport. Being EV ready, they are low rolling resistance, hard rubber and LOUD. They do not perform anything like the Pilot Sports of 5-10 years ago, which were stellar tires. I am very, very disappointed. MICHELIN SHOULD HAVE SEPARATE LINES FOR EV AND EFFICIENCY AND OTHER LOW CLASS CARS, AND A DIFFERENT LINE FOR PEOPLE WHO WANT THE WONDERFUL QUIETER, SOFTER AND SMOOTHER TIRES UPON WHICH MICHELIN BUILT ITS PRIOR REPUTION. One positive: it is good that Michelin has its 60 day swap program. Given the poor quality and NOISE of these new Michelin kinds of tires (all of which are designated by Michein as EV Ready), I will probably move to a cheaper tire mfgr whose tires are grippier and not as LOUD and save the money.
