Had to replace the tires on my 2018 Civic Sport and I can't believe the difference. I previously had some “high-performance” Falken tires that weren't bad but after a couple days with the Michelin Sport A/S 4s I finally understand. This is the first Michelin performance tire I have ever driven on and my car is a completely different machine on these tires. The level of grip is superior to any tire I have ever had, even in the rain. My car feels like it is floating until I cut the wheel and suddenly it becomes glued to the blacktop. I am a very aggressive driver and understand the value of having tires you can trust on your car and I love these tires!!!

I just replaced Continental run-flat tires with the Pilot Sport All Season 4 (non run-flats). It is made a massive difference. The tires ride smoothly, steer precisely, braking is improved, and wet performance is so much better and confidence inspiring. A great combination of both sport and luxury. As to a number of comments about the tires being noisy, they really aren't any noisier than competitive tires or the tires predecessor, the A's 3+. I think it's just that the tone of the noises a little bit higher pitched and therefore more noticeable to some people. On the other hand, I noticed that there is no noise difference when driving on asphalt and concrete, which is unusual because most tires tend to be louder on concrete. Not so with these tires.

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.

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,

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'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.

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.

Too many reports not indicating what vehicle the tires are mounted on! What good is such info? I have a new set of 245/4018 going on our 2019 RS 3, which has run 16,698 fast back roads out of a total 23,192 on current Michelin A/S3+ with no issues at all. Will report on the Pilot Sport 4S after some mileage is run at speed.

I drive a RWD P85+ Tesla Model S, which is both heavy and up until last winter had staggered 21” wheels. I was used to buying a new set of Pilot Sport 4S for the rear every 10-12k miles, which is to be expected, but not welcomed on that setup. I switch to 20” square rims front and aft, and also switched to Pilot Sport AS 4's ,245/45/ZR20 99Y, and couldn't be happier. Now that I can rotate tires life if grand. I'm used to extremely irregular wear and regular pinch flats, but I've got things nailed down now. Tire wear with theses tire is even, traction is more than adequate and tire noise is drastically reduced.

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.
