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.

Great tires but they don't last. I'm at 46000km and they are down to the wear bars and not even three years old. Like I said, no other issues except for tread life. I would give it five stars if lasted 80000km or even 70000km . Driven on a Lincoln MKX with no aggressive driving.

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.

Bought four 235/50/18ZR 101Y Pilot all season 4 tires for my Buick Allure Super and have had them for 3 years on the car so far have only put 10000km on the tires. Tires have shown very little wear and are excellent in wet and dry conditions I only drive this car in spring,summer and fall and the lowest temp I have driven is -5 Celsius and have no complaints very happy with this tire . Also road noise is non existent with these tires their extremely quiet

I put a set of these Michelin Pilot 4 season tires on my 2007 Corvette to replace 10 year old Pilot Super Sport Tires. There is no comparison in ride quality and road noise compared to the Pilot SS tires they replaced that tended to be harsh riding and noisy.

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 have a 2020 Type R, factory tires are not meant to driven below 5C so I have to get a set of tires for the winter. There is not much snow in the winter where I live but it's always under 5C and raining. I tried driving on winter tires and all-weather tires available for my car and they both failed to meet my expectation for wet traction. Put these PSAS4 on for couple weeks and I am very happy them. They are definitely better than the Conti DWS06 on my BMW. I drive a "sport car" the way it's meant to be driven, should not have to compromise and drive slowly because it's cold IMHO. I will drive my SUV when it snows heavily.

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.

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.

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.
