Upsized to 18" wheels & ride is even a bit softer than the AS3's on the 17" wheels. Steering at low speed is a bit heavy with the larger contact patch than the OE 215's. Good grip cold, much better when warm. Side wall flex is a big improvement in cornering.

BMW M235 My previous tires were Pilot Super Sports which I found to be fabulous in traction, ride and response. But, living in the snow belt, the lower temperature season can really shorten the time I have them on the car. So when I needed a replacement I thought why not go with the AS4 , maybe loose a little performance but enjoy a longer time with no snow tires on. I've now driven about 600 miles with them. I find them as harsh and uncomfortable as the RFTs that were OE on the vehicle. Jarring really even on the softest suspension setting. Further my dealer could not balance them for a smooth ride after 3 tries on the Hunter Road Force. I will say that after the break in, they had good traction in dry and wet. Never got to snow. I'm calling uncle and swapping them out for another brand.

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 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 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.

Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

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 just got a set of All Season 4s after running the previous set since 2020. Before replacing them, I took the old set to the track, and even below 2/32" tread depth, they provided remarkable grip and performance.​ The new tires feel outstanding. They're somewhat quieter— even though I never noticed that the previous set became slightly noisier as they wore, it was never intrusive. These tires inspire confidence, offering exceptional grip during spirited drives while maintaining comfort and quietness on long highway trips.​ Driving a vehicle designed for both performance and comfort, it's impressive to have a tire that doesn't compromise on either aspect. The Pilot Sport All Season 4 truly delivers on both fronts!

These were quite a bit softer and quieter than the Pilot 3 + tires removed after 40,000 miles. The Pilot 4 AS felt initially like it wouldn't be the same in handling as the 3+ AS but that was totally wrong. They handle great. I would definitely buy them again.

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.
