I've had my tires for about 9 months now and they're awesome!! My previous set of tires were the Continental Extremecontact DWS06. If I were to compare the two, in terms of performance and comfort, the Pilot Sport A/S 4 has been quite a bit better in the dry and wet weather...gas mileage is approximately the same for both tires. I haven't had the opportunity to drive in the snow so I don't know which tires are better. But in terms of treadwear, I would give a slight edge to the Continentals.

Big fan of Michelin Pilot Sport AS 3+. Have them on two family cars. Just installed the new Pilot Sport AS 4 on my daughter's 2020 Honda Civic LX. Replaced the OE tires. It's a entirely different driving experience. Love these tires. Fantastic Product

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.

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.

What a perfect pairing for my older QX50. We've had a rainy December in San Francisco. I usually drive my Jeep. However since installing these Pilot AS4 my old Infiniti 3.7 AWD thinks she is a sports car. My favorite feature other than the handling is wet roads and deep water at 70mph plus there is not a single hint of Hydroplaning. The wheel doesn't so much as tug. I'm talking puddles on I-580 that span 4 lanes of road. Other than a quick flick of the wiper blades; there isn't even a perception you just hit a puddle. Dry cornering at the limit at least on my Infiniti, with the driver assist off and foot on the gas hard, she drifts predictably giving lots of warning. These tires test your driving skills, not the other way around. If you are driving AWD and have 300+ HP I cannot recommend these tires more highly.

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.

Purchase these for all-season use in California. Rode these through the recent cyclone storm with no issues. No hydroplaning and complete confidence in braking and cornering. Ride is quieter than I thought. I drive a EV so only noise is from the tires which was not really noticeable. Only thing I would change is the lip of the tire seems to offer little protection for my brand new wheels. It sits flush with the lip of the wheel and I can already foresee curb rashes. If they can bring out the lip of the tire a bit more to protect the rim, I would give it 5 stars. Othere than that, a super high performance tire. I take off fast, corner fast, and stop fast so a high performance tire is required.

Why dont they make this in a 225/50/18 I just got a 2017 subaru legacy 3.6R Limited and they made the pilot sport a/s 3's in that size in a W speed rating, I'm looking for new tires to improve the ride and handling and everything about my car, but why should I go with a michelin if I have to settle for the old technology in the a/s 3? The a/s 4 is the newer successor with more and better technology, I got a subaru with all wheel drive so I can run a sportier tire all year long with my geographic area with occasional snow, I might just have to settle for an all season tire without a sport focus, which I dont want to do, I want an all season with a sport focus, but why should I go with an a/s 3 when there is a newer tire in the a/s 4? The answer to that is because unfortunately the a/s 4 is not available in my size, and I don't want to go with a nonfactory size either, troubling matter for a loyal michelin fan like myself, just wondering if their are plans at all to bring the a/s 4 to the market in more sizes at all? If so, i'd be interested in possibly getting some, have not actually bought the product, my ratings are just based off of my experience with michelin products in general, which have been pretty good, really honestly interested in either the cross climate 2 in the 225/50/18 in a v speed rating or higher or the a/s 4 in a w speed rating or higher, I have no use for the cross climate suv tire in my size which is designed with too high of a load rating for my sedan which would ultimately only result in an unnecessarily harsh ride since my vehicle is somewhat lighter weight, not much tire support for my vehicle in this size from michelin unfortunately, at least no tire support in the tire models that I want :(

I've installed the Pilot Sport A/S 4 on my 1995 Camaro Z28 I've own this car since new, over the 26 yrs of its life I've had several different tires. I can honestly say that this tire lives up to the Michelin standard, awesome performance in wet traction excellent overall. If you have the opportunity to purchase these tires in your size if available just do it you won't be disappointed. Only negative thing about this tire is the availability in all sizes.

I purchased a set for a our BMW approximately a month ago looking for a set of all season performance tires which we could also use in light snow but enjoy during spirited drives in the summer without the hassle and expense of 2 sets of wheels/tires.
