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.

Just purchased one 275/40/18 tire for Mercedes Wow these tires are light weight ,softer rubber texture Very limited amount of road noise. These tires somehow makes me feel more secure driving in the rain because it Has like minimal slipping It gives you an straight ahead planted feeling while driving in the rain even above highway speeds (You generally shouldn’t do ) On dry roads it creates perfect grip , turns where I point the steering wheel My car is a 5,145 pound Mercedes s55 and the tires makes me feel confident and more in control. But like they say on reading rainbow ,don’t take my word for it, buy the tires for yourself ! And you’ll see what I’m talking about first hand

I bought these tires for my Honda Civic Si to replace the god awful OEM Goodyears and I was not disappointed. These tires turned my car into a monster. Now I can have a lot of fun driving without losing traction, regardless of if it is raining or not. Rain performance is incredible as it felt like driving in the dry with these tires. The slight increase in noise is well worth the performance.

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

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’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.

I ordered new wheels for a Mercedes Metris van but the supplier noticed they were slightly damaged before shipping them. I ended up selecting a slightly wider wheel and noticed the Pilot Sport All Season 4 tires were available for this wider wheel. I bought them since I’ve run through a few sets on the Porsche and they were excellent. Now, do I need tires speed rated at 186 mph on a van - no - but for just a little more than a lesser tire I picked up some tires I feel confident with, especially with passengers. Ok, it’s overkill but they looking freaking great!

I’ve gone thru two sets of these tires with the last set going 18200 purchased 2/22 miles and are now down to the wear bars. I live in Phoenix and thought the heat was a factor. My daughter in Washington also got poor tread life out of the same model tire with a Kia sedan my car being an Audi SQ5. I’m replacing these with the Defender 2 giving Michelin another try I hope it ends up better. Also will seek some adjustments based on short tread life bit will see how that goes. All other performance for this tire were wrest they just don’t last.

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!

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.
