After 22 months & 17k miles: Exceptional high speed handling and control. Extraordinary protection from hydroplaning. Excellent snow and ice performance for a non-snow/ice tire. It takes real work to break traction, even with traction-control disabled during wet weather. Do NOT confuse the Pilot Sport AS4 (High-Performance All-Season M+S rated - 45k warranty) for the Pilot Sport 4S (HP soft compound Summer "only" tire - 30k). Several of the negative reviews on here clearly suffer this confusion over the 4S.

Great tires on the GR Corolla, I would love to try the CrossClimate2 next. This has been great on the Florida roads, trails and even in the harsh conditions as well. People that are experiencing wear on these tires need to get their alignment checked up before mounting these tires on, my tires still look brand new after getting an alignment during the new installment. Will purchase again unless Michelin man sponsors me with a new set hehe

2015 Mazda3 sTouring I have about 1000 miles on these, and was absolutely floored when I looked over the difference in fuel efficiency compared to the OEM tires. There is a drop of almost 20%! I checked the tire pressure with multiple gauges (2x analog, 1x digital), so they're not under inflated. The warehouse also inflated them with nitrogen if that makes a difference. I'm doing mostly highway commuting, so the nuances of 'better' handling may be lost on me, but they do feel like when I put my snows on- kind of mushy - on the road. After I get home (about 20 miles), the tires are very warm to the touch, even when it's raining. Don't know what they'll feel like in the summer. The warmth does make sense, if these tires have such a high rolling resistance, the energy is spent as heat. As a commute car, there really does not seem to be any difference in handling wet or dry pavement. There doesn't feel like any benefit to braking, and possibly a decrease in ability to accelerate. I am really disappointed in these tires so far. After reading all the positive reviews, I really wonder if anyone considers fuel efficiency. Maybe wearing these down to the support layers will improve fuel performance, but I'm not holding my breath for that.

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.

This is my second purchase of these Michelin AS 4 tires. Great product. Well satisfied.

Definitely getting my money worth

I have had Pilot Sports multiple times. Awesome tires.

Last set of same tires only lasted 20k miles. Very disappointed

Holds the road and very smooth great tires
