Delaminates and must be replaced before tread life. I have had 3 sets of AS3, then AS4's and ALL have delaminated in the front just where the tread meets the sidewall. I use my Corvette Grand Sport for performance driving, but these tires are rated f.or high performance. I currently have less then 4,000 miles on my tires and the fronts need replacing

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

I waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.

I purchased a set for a our BMW approximately a month ago looking for a set of all season performance tires which we could also use in light snow but enjoy during spirited drives in the summer without the hassle and expense of 2 sets of wheels/tires.

Great tires on the GR Corolla, I would love to try the CrossClimate2 next. This has been great on the Florida roads, trails and even in the harsh conditions as well. People that are experiencing wear on these tires need to get their alignment checked up before mounting these tires on, my tires still look brand new after getting an alignment during the new installment. Will purchase again unless Michelin man sponsors me with a new set hehe

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 have a 2020 Type R, factory tires are not meant to driven below 5C so I have to get a set of tires for the winter. There is not much snow in the winter where I live but it's always under 5C and raining. I tried driving on winter tires and all-weather tires available for my car and they both failed to meet my expectation for wet traction. Put these PSAS4 on for couple weeks and I am very happy them. They are definitely better than the Conti DWS06 on my BMW. I drive a "sport car" the way it's meant to be driven, should not have to compromise and drive slowly because it's cold IMHO. I will drive my SUV when it snows heavily.

The specs and real performance of these tires are incredible. 255/35R21/XL 98W Front - 275/35R21/XL 103W Rear. I know My Tesla MYP can outperform 97% of the vehicles on the road. The car can do 0-60 in 3.4 seconds. Most likely your non-Tesla car cannot. I put it to the test on my daily 55 mile commute. The tires have a lot to do with this. The heavy EV and high speed rating are brilliant technology. Fully confident all weather rain/sleet /snow/ice at very high speeds. Hey Michelin Bring back Premium Touch.. love it

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I’ll have to chalk this purchase up as a negative one and will be looking for something else in the near future.

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.
