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!

I bought these today 1/25/21 at 12pm and drove for approximately 100 miles and boy let me tell you. I came from Pirelli scorpion run flat tires and it is a night and day difference. These Michelin’s are on the money. What a smooth floaty drive on my 17’ X5 MSPORT. These tires are very sticky as I hear them when I roll down the windows. Very responsive steering improvement from runflats. These tires are everything. I feel much safer having my family in the car. Thank you Michelin.

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.

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.

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!

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.

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.

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 bought a set of pilot sport AS4 to put on my car and I absolutely love them the amount of control and response difference compared to the stock tires was unbelievable and as far as grip goes I have a hard time breaking loose when I try to do it on purpose

These were quite a bit softer and quieter than the Pilot 3 + tires removed after 40,000 miles. The Pilot 4 AS felt initially like it wouldn't be the same in handling as the 3+ AS but that was totally wrong. They handle great. I would definitely buy them again.
