I originally bought the Michelin Pilot Sport A/S 3+ with a wheel and tire package in 2016. Those tires were very impressive and held up well. When I had to get new tires, the Pilot Sport A/S 4's were a no-brainer. I've had a while to give them a full and honest review. In dry conditions these tires perform just as well as any summer tire on the market. There is no lack of grip in cornering and little to no road noise depending on the condition of the road. In wet rain conditions these tires grip the road very well and keep the car grounded through corners. In snow conditions the tires do pretty well, depending how much snow. I have had some traction issues in over two inches of new snow. Obviously in these conditions, you use your best judgement and use an abundance of caution and maybe even opt for a winter tire if conditions call for it. Overall they perform well in cold conditions up to -10 below. I've never had a traction issue on cold dry roadways using these tires. Ice and snow may bring a little bit of traction issues from a dead stop, but once you are up to speed you will have enough grip to make it home. After close to two years of driving with roughy 30-45k highway miles (and not always following the reccomended tire rotation intervals) all tires are at a 7/32 tread depth and still have plenty of life left. Someone may look at the overall price point and opt for a cheaper tire option, I wouldn't call it the most "economical" option. In terms of "you get what you pay for" these are worth every penny. There's a reason you see plenty of performance manufacturers putting Pilot Sports on from the factory. It's not a gimmick. These tires will last much longer than other brands, and will continue to deliver the performance and safety you expect from a brand like Michelin.

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.

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 :(

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

These tires lasted me 57,000 miles on my Tesla Model 3 RWD. Would probably last another 2500 miles but changing before rainy season in california. Tires are very grippy in rain and dry, but the noise and drone of tires is a bit excessive. Overall I love the performance, safety and longevity of the tire so decided to get a second pair.

Purchased these AS/4 tires to replace factory Pilot Sport Cup tires at 10,002 miles. These tires are much quiter with improved ride and very good lateral grip. They will go up in smoke with a hard launch or agressive accelration out of a hard turn. However; under normal driving conditions they are great. Highly recommened to anyone daily driving a high performance sports car.

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.

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.

First replacement set of Pilot Sport AS 4 tires for my 2018 Mercedes GLS 550 lasted just over 37K miles in a little over 3 years and had hoped they would have lasted the entire 45K warranty mileage. I didn't make a warranty claim as the interior of the treads wore more than the exterior by more than the allowed difference in tread depth. We did rotate the tires as recommended by Mercedes which was every 5,000-8,000 miles. I really hope these new set of replacements will last the entire 45K mileage or more. Thanks, Clyde Toms

I bought the tires early March so far so good. I've had 2 days with light snow, 1 week of rain and a few mild days. No complains. Just bought a second set for another car + Pros: Grip, Stability, Braking, Cornering, Tread Design, Quiet, Steering Response, Visually Appealing, Comfortable,
