What a difference in the performance from my OEM tires. I put these on my Audi SQ5 replacing the "performance" tires that I had on there that only got about 10,000 miles. I had these new tires for about two months now and the performance of these tires blows away my other tires. It was very difficult to find a 21" all season performance tire at a affordable price. Today My wife drove the car on the freeway in a down pour and she felt very comfortable driving as it proved to be a tire that made the car very stable and responsive. It made this purchase worth every penny. So if you have a vehicle with a performance 21" tire I highly recommend the Michelin Pilot. Thank you Michelin for an awesome tire.

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 waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.

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.

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.

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.

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.

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

I bought these tires 5 days ago and they flat spot overnight. I’ve never had a tire do this to me in my life. I had high expectations for these as i have always wanted Michelins. The issue goes away when the tires warm up but the colder it gets the issue doesn’t seem to go away once it warms up.

Went from 17 inch To 18 Inch, huge jump in performance (both wet and dry) from the tires Ford put on my 2015 Mustang eco-boost. People told me the road noise would be an issue but quite the opposite. Black car, wheels, tires. Sorry, can't figure out how to transfer pic. from my phone (LG)
