I've got a 2009 Jaguar XKR Portfolio Convertible with 69k miles. This is my third set of tires. My first were Yokohama's....not a bad tire but in my opinion, they don't compare with the Michelin Pilot Sport AS4. I'm on my second full set of 4 Pilot Sports. When these wear out, I'll buy another! They handle extremely well, the ride is wonderful and they lasted about 45,000 before needing to replace. I'd absolutely recommend these for your sports car!

2015 Mazda3 sTouring I have about 1000 miles on these, and was absolutely floored when I looked over the difference in fuel efficiency compared to the OEM tires. There is a drop of almost 20%! I checked the tire pressure with multiple gauges (2x analog, 1x digital), so they're not under inflated. The warehouse also inflated them with nitrogen if that makes a difference. I'm doing mostly highway commuting, so the nuances of 'better' handling may be lost on me, but they do feel like when I put my snows on- kind of mushy - on the road. After I get home (about 20 miles), the tires are very warm to the touch, even when it's raining. Don't know what they'll feel like in the summer. The warmth does make sense, if these tires have such a high rolling resistance, the energy is spent as heat. As a commute car, there really does not seem to be any difference in handling wet or dry pavement. There doesn't feel like any benefit to braking, and possibly a decrease in ability to accelerate. I am really disappointed in these tires so far. After reading all the positive reviews, I really wonder if anyone considers fuel efficiency. Maybe wearing these down to the support layers will improve fuel performance, but I'm not holding my breath for that.

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 have already driven 17,118 miles with these tires and experienced my first snowstorm with them. Doing my regular maintenance rotating my tires every 5k miles and making sure my tires are properly inflated every month, I have run into 0 issues. They drove flawlessly in the snow with minimal slippage. I enjoyed them and will keep buying Michelin tires in the future.

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.

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

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.

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.

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.
