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.

Bought these for my Mercedes S550 4matic at 80,000 miles Today at 104,000 am showing cords through 2 front tires Rotated less than a month ago and no mention of any issues. AS3 not 4 Seems like dramatic sudden failure for no apparent reason. Dealer tells me Michelin is not what they used to be as far as handling warranty issues and I will likely eat the full cost of a new set How come my rear tires did not show this wear since they had been on the front prior to this rotation?

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 bought these tires to replace the Pirelli's on my Ford Explorer ST and they make the drive to Montana (over 1,000 miles one way) very pleasant! We drive multiple times from California to Montana a few times a year and absolutely love these tires. I'll definitely buy these again when they need to be replaced.

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.

I purchased 4 Michelin Pilot Sport 4S 255/45ZR20 (105Y) XL I like the tires however the date code on the tires were: 1 tire in 2017 2 tires 2018 1 tire 2019 I’m very disappointed in how old these tires are coming from Tire Rack! I’m happy with the ride. Lee was very helpful when ordering.

I switched from PS 4 to PS All Season 4 for my 2015 Mustang (not staggered). Great tires? Yes. Very comfortable, with good performance. Before buying I had read that the AS version gives up little in dry performance - of that had been very true I would give a 5/5 testing. The compromise in all out traction is greater than I expected. But great tires that I would recommend? Definitely and I have no regret stepping down from hard core performance (the PS4 is amazing!) for more comfort and safety in lower temperatures and even light snow. Lower noise. Either tire is a great choice.

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.

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.

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I’ll have to chalk this purchase up as a negative one and will be looking for something else in the near future.
