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.

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.

Got these not too long ago and they're a great daily tire. Quiet and very comfortable for a performance tire, my car is lowered too. I got these to replace my AS/3s since those were so good. The tire has excellent dry grip and very good wet grip. I haven't had a chance to test snow grip yet, but if the AS/3 was anything to go by, I am not worried about it one bit. I just had a chance to take the car to the track and the tires were great there as well. I never felt like the tires were going to let me go off track unless I wanted to, and I was full tilt out there. Managed to pass up a 350Z in my 200hp Acura and didn't get caught by the Focus RS or the Roush Mustang. That was a very twisty course where grip was key, and it never let me down. The tires lost a little grip after some very hard laps on a hot track, but I doubt any other all season would do better being pushed like that. They would have been fine after half a slow lap, and the brakes were cooking worse than the tires by that point.

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.

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 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 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.

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.

I bought this set of tire about a year ago and can say they are the best All Season Sport tire on the market. The tires were purchased for my 2021 Roush Stage 3 Mustang which has 760 HP, 670 Ft. Lbs. TQ. The car can push any tire to its limits but the Pilot Sport A/S 4 handles the power in a very linear fashion. Yes, a Pilot Summer only tire would stick to the road better if I ran it on the track but that is not going to happen. For my very spirited driving I have found the Pilot A/S Sport 4 tire handle the twisting back mountain roads with ease. I highly recommend these tires for anyone who wants the best of All Season and Track only tires in one set of tires. Unless you plan on putting your car on a drag strip or the big oval this is all the tire you will ever need.

I bought a set of Michelin Pilot Sport All Season ZP for my 2014 Cadillac CTS VSport Premium. These are the best riding run-flat tires I have used on this vehicle. I have experienced better wet weather performance, and expect better wear than with summer tires.
