I've never written a tire review in my life. I can't help but write something about these tires. I previously had another all-season tire from a certain company with a blimp and the difference between these Pilot AS4s and those are shocking. Smooth as silk ride, whisper-quiet, and traction that is amazing on my heavily tuned Audi 4.0T car!

I've had a few good tires in my life, but nothing like the wow factor of this new design. The wet traction is outstanding. This tire inspires a lot of confidence. So much technology with the tread design and the compound. I'm not looking forward to the snow, but with this tire I feel that it will not be a problem. This might be the perfect tire for the Pacific Northwest. I live in Vancouver BC and we get lots of rain. My old set of P Zeros feel like crap in comparison to the Michelin AS4. My Mustang loves these tires !!! :)

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.

Bought these tires about a year ago and have no complaints at all!! They’re much grippier than my old tires and are whisper quiet. Unfortunately, my MPG has taken a slight hit, but that’s a small price to pay for much more confident braking and handling.

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.

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!

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 just got a set of All Season 4s after running the previous set since 2020. Before replacing them, I took the old set to the track, and even below 2/32" tread depth, they provided remarkable grip and performance.​ The new tires feel outstanding. They're somewhat quieter— even though I never noticed that the previous set became slightly noisier as they wore, it was never intrusive. These tires inspire confidence, offering exceptional grip during spirited drives while maintaining comfort and quietness on long highway trips.​ Driving a vehicle designed for both performance and comfort, it's impressive to have a tire that doesn't compromise on either aspect. The Pilot Sport All Season 4 truly delivers on both fronts!

I have the cup tires on my GT3, the Ice tires on my mazdaspeed6. And so I bought these for my '18 Model S 100D. They replaced the "quiet" Goodyears OEM at 23,500 miles. After installing the Pilot Sports, I immediately went to the Tesla Service Center in St. Bruno , Quebec for a wheel alignment. I have never touched a curb with the wheels but the car needed an alignment. At this point they are about as quiet as the goodyears. They seem to handle bettter too, but the wheel alignment helped with that too. I have never had a bad experience with Michelins. Even though I purchased them last Winter I just had them installed.

Came on new 24 Porsche Panamera 4. Total of 4,600 miles to date. Great handling and good in the rain. Works well on light snow too. Tires are different size front and rear so cannot rotate. Time will tell how long these will last. I would be happy to get 30k miles.
