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.

I bought these tires for my Honda Civic Si to replace the god awful OEM Goodyears and I was not disappointed. These tires turned my car into a monster. Now I can have a lot of fun driving without losing traction, regardless of if it is raining or not. Rain performance is incredible as it felt like driving in the dry with these tires. The slight increase in noise is well worth the performance.

Purchased for a 2010 Camaro V6 driven all year round in a cold climate. For the past 3 months (December to March), they have performed excellently in cold weather (below freezing) and in light snow. I will no longer be swapping tires in the summer, and will stick with these all year round. They are superior to my previous winter tires on the car, along with the previous summer tires.

Replaced the old Stock Pilot Super Sports on my ‘19 Z06 Convert with a fresh set of Pilot Sport A/S 4’s. Absolutely love them. Pilot Sport A/S 4’s are rated for hot and cold ambients, dry, rain, and even snow. The perfect tire for northern state roads and highways. The Ackerman effect with tight turns, hydroplaning on rainy roads and pebble showers on the bottom of the car common with Pilot Super Sports is gone. The A/S 4’a are definitely quieter than the Pilot Super Sports. The A/S 4’s may have a bit less traction on hot dry track days but I’ll never miss it. I’d much rather have the extended driving season with the A/S 4’s . Thank you Michelin!

I have 2 sets of these tires, for my 1993 Corvette ZR-1 and my 2015 Challenger 392. Excellent grip in all weather conditions that I drive in (I rarely see snow, but frequent heavy rain and temps below summer tire ratings) as well as quiet and comfortable.

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.

These handle really well and helped me out a lot with the big rain we get in Florida. Unfortunately, 2 tires are down to 3 and 2/32nds. 2 Tires are down to 4.5/32nds. I have about 20k miles on the tires and drive on the highway mostly. Florida roads can be pretty rough since they get baked, so I imagine this is a leading cause. I'm hoping to get some warranty on the 2 tires that are near the end.

Installed these Pilot Sport A/S 4 about three weeks ago and coming from a previous set of the Primacy MXM4 I have to say ::::) WOW!!!! For the past two weeks we've had terrible rains in South Florida and these tires have performed outstanding, in heavy rain, light rain, no acquaplaning whatsoever. When conditions dried the tires performed awesome. The sidewall and overall structure of the tire is a bit firmer, which I like comparted to Primacy and there is no squishiness at all! The noise is very much comparable to the Primacy, I would say a very small fraction louder but not noticeable. These tires were a great buy for sure. 235/40R19

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.

I have been a Michelin owner for more than 40 years and have only had 2 issues in all that time. One was a bent suspension arm that tore 2 tires to shreds. The other was a 3 inch spike that blew a tire, neither of these were Michelin issues and have trusted the brand forever.
