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 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.

Tire has amazing qualities in which i love. Tread will not keep up the 45,000 miles in which is stated. 255/40/ZR21 & 265/40/ZR21 Are the tire sizes i own. I can not purchase Hazard Insurance due to size of tire, thankfully i have not had an instance which requires it but its good to have. Please create a tire for winter for these sizes. Much appreciated!

I have been a Michelin owner for more than 40 years and have only had 2 issues in all that time. One was a bent suspension arm that tore 2 tires to shreds. The other was a 3 inch spike that blew a tire, neither of these were Michelin issues and have trusted the brand forever.

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.

Things i heard about Michilin tires from tire guys who have handled all different types, said that Michilin has the best overall highest quality and attention to detail. I have only owned my new set of tires for about a week, but they are perfect. Grips amazing, super quiet, smooth, feel sturdy and safe. 2008 Ford Fusion. Not real powerful, but if you keep your gas and oils clean and new theyll run for quite a while. Amsoil in engine, tranny, ps, and coolant. Runs like butter. Mazda 6 frame and suspension, so handles righteously.

I replaced my Pilot HX MXM4 93V XL, which i had for 11 years for off winter use. New Sport All Season 4 are much better on wet surface, but the noise level when driving 50-80 km/hr is quite loud...louder than the Pilot HX MXM4's, and louder than my winter tires. So I plan to keep them on this winter and will report back how well "All Season" means.

I’ve previously owned the AS3 and AS3+. These new AS4 are noticeable better. It handles and grips just as good as previous models. The improvement is in the noise and comfort level. Noise being more muted, meaning in a more comfortable ride. It’s an early assessment but hope the durability and longevity will be impressive. We will see.

Didn't even last 18k miles. Purchased in Aug 2021 and put 18k highway miles on them. They're completely treadless and I have to buy 4 new tires again. These are not cheap tires to replace. I'm livid. If I could give these negative stars, I would.

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
