I purchased these tires so that I could drive my Vette so I wouldn't be worried about late season mountain drives. I have just over 2,000 miles on them and couldn't be more satisfied. The ride is great, the handling seems to be better and there's virtualy no road noise.

Went from 17 inch To 18 Inch, huge jump in performance (both wet and dry) from the tires Ford put on my 2015 Mustang eco-boost. People told me the road noise would be an issue but quite the opposite. Black car, wheels, tires. Sorry, can't figure out how to transfer pic. from my phone (LG)

There is a reason OEMs choose Michelin. The Tesla model S must have smooth, quiet tires that absorb various road imperfections and maintain good handling characteristics. Road noise is a big concern when driving a vehicle that has no drivetrain noise.

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 no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

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.

Replaced the old Stock Pilot Super Sports on my ‘19 Z06 Convert with a fresh set of Pilot Sport A/S 4’s. Absolutely love them. Pilot Sport A/S 4’s are rated for hot and cold ambients, dry, rain, and even snow. The perfect tire for northern state roads and highways. The Ackerman effect with tight turns, hydroplaning on rainy roads and pebble showers on the bottom of the car common with Pilot Super Sports is gone. The A/S 4’a are definitely quieter than the Pilot Super Sports. The A/S 4’s may have a bit less traction on hot dry track days but I’ll never miss it. I’d much rather have the extended driving season with the A/S 4’s . Thank you Michelin!

Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

I bought these tires 5 days ago and they flat spot overnight. I’ve never had a tire do this to me in my life. I had high expectations for these as i have always wanted Michelins. The issue goes away when the tires warm up but the colder it gets the issue doesn’t seem to go away once it warms up.

Mounted these tires on my Mazda 3 GT in May of 2021. Got about 7,000 on them now and I have been well pleased with their performance. Seems I chicken out before these things reach their limit as I have yet to have them squawk back to me during sever cornering, severe stopping, severe acceleration, ( well it's a four banger should just call it snappy acceleration).The performance is just outstanding in all conditions. I would like to find some fault with them but I have nothing to complain about. Good job big ol squeezy Michelin Man.
