Great Tire but Tread ehh..

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!

Magical tire

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!

So far so good!

I have the cup tires on my GT3, the Ice tires on my mazdaspeed6. And so I bought these for my '18 Model S 100D. They replaced the "quiet" Goodyears OEM at 23,500 miles. After installing the Pilot Sports, I immediately went to the Tesla Service Center in St. Bruno , Quebec for a wheel alignment. I have never touched a curb with the wheels but the car needed an alignment. At this point they are about as quiet as the goodyears. They seem to handle bettter too, but the wheel alignment helped with that too. I have never had a bad experience with Michelins. Even though I purchased them last Winter I just had them installed.

Much Improved for My Driving Purpose

Purchased these AS/4 tires to replace factory Pilot Sport Cup tires at 10,002 miles. These tires are much quiter with improved ride and very good lateral grip. They will go up in smoke with a hard launch or agressive accelration out of a hard turn. However; under normal driving conditions they are great. Highly recommened to anyone daily driving a high performance sports car.

Phenomenal Tire technology

Had these on my Golf R AWD for a few month now and with the recent 4" dump of snow I have had the chance to drive these in all conditions. Performance has been outstanding, great dry and wet control, excellent braking and these got me out of my steep driveway where the OEM's left me stuck. Highly recommend these for all season sports car applications as they don't compromise performance.

Great tire

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.

Replacing Pilot HX MXM4 (comparison=Noisy,Wet=Better)

I replaced my Pilot HX MXM4 93V XL, which i had for 11 years for off winter use. New Sport All Season 4 are much better on wet surface, but the noise level when driving 50-80 km/hr is quite loud...louder than the Pilot HX MXM4's, and louder than my winter tires. So I plan to keep them on this winter and will report back how well "All Season" means.

Telsa: 15-20% range loss but great grip.

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.

2017 Infiniti QX50 AWD

What a perfect pairing for my older QX50. We've had a rainy December in San Francisco. I usually drive my Jeep. However since installing these Pilot AS4 my old Infiniti 3.7 AWD thinks she is a sports car. My favorite feature other than the handling is wet roads and deep water at 70mph plus there is not a single hint of Hydroplaning. The wheel doesn't so much as tug. I'm talking puddles on I-580 that span 4 lanes of road. Other than a quick flick of the wiper blades; there isn't even a perception you just hit a puddle. Dry cornering at the limit at least on my Infiniti, with the driver assist off and foot on the gas hard, she drifts predictably giving lots of warning. These tires test your driving skills, not the other way around. If you are driving AWD and have 300+ HP I cannot recommend these tires more highly.
