Great Handling Tire

I bought the Tires about 5 months ago and out of all the tires I have had on my 90 Corvette these are the best yet, Handling is great, Ride is very Good and they seem to be wearing very well.

MY MICHELINS

The experience of my first two installed Michelin Pilot AS 4's on my vehicle prompted the second purchase of the other two to complete the set. I replaced my tires with these on my vehicle because of the Michelin tradition for tires along with the performance and quietness they bring.

Best all-season tire for performance cars

Very durable tire with great handling and responsiveness in all weather. I have put these tires on multiple vehicles that I have owned (Toyota Camry, BMW X6, Audi A6, Lexus GS300) over the years and they've exceeded the 45K warranty every time. They have excellent traction especially is wet weather conditions greatly minimizing hydroplaning instances.

Michelin - Go To Tires

We put these tires on our BMW 328i not long after we purchased the car to replace the awful run-flats. It was an amazing difference in ride and noise level. Our 2020 Honda Accord 2.0 Touring was purchased from a friend in 2022 that had the standard 19 inch wheels. They may be great for performance but they rode like a wagon and were prone to curb rash. We're pretty conservative drivers. Based on our BMW experience, we switched to 17 inch wheels (which seems to be fairly common) and also purchased the Pilot Sport tires for the Honda. The ride quality improved drastically for the better.

Fantastic all-around tire

Excellent tire. The compound is sticky and aggressive while still offering good traction in cold weather. The tires appear to be well made with a very still XL-rated sidewall. Handling is extremely precise and predictable with perfectly controlled behavior when approaching the limits of cornering grip. The tires are very comfortable and pretty quiet for a performance A/S tire. While I cannot comment on tread life or highway stability just yet, no doubt those will meet expectations as well.

Best mileage yet.

Tire performs well. Tires are on BMW 330Ci. Have tried a few other brands. Would normally achieve half (20 to 24k) of recommended tread life. These Pilot Sport AS4 tires have provided the longest durability achieving 40k of tread life. Plus, they handle well and provide a great driving experience.

Good all-around tire

These are excellent "all-around" tires that provide reasonable traction in rain/snow/ice, allowing me to go through up to 6 inches of snow this winter without difficulty. This is surprising, given that my Cadillac CTS4 Performance Coupe is quite low, and has staggered tire sizes. The rear "steamrollers" should NOT do well in the snow, but yours do. On dry pavement, the ride is as smooth as can be expected in a low-profile tire, and handling is quite good. It is not as good as a dedicated, high-performance summer tire but, again, it is a great compromise.

Hard Noisy Ride

I was not told or read anything about this tire for my Corvette Grand Sport being a run flat tire. I found out from the dealer a few days after having the tires installed when I returned to have to lug nuts checked for exact tightness. The tire is very noisy and a hard ride.

Horrible!!!

These are by far the worst “all season” tires I have ever had. In 1 years time I have needed to plug or patch all 4 tires, including plugging 1 tire twice. They grip the road great, but the problem with that is that they grip every nail and other pieces of debris what seems like 100% of the time. I say other debris because one of the plugs I needed to apply was because of a relatively sharp piece of plastic, and another was because of a broken VW emblem that I ran over. All other incidents were because of 2 drywall nails (tiny) and 1 normal screw that I would expect to puncture any tire. My driving habits have not changed and I do not live near any new construction locations. I have never experienced a more sensitive tire, and I am 37 and have driven foreign cars with ridiculous speculation tires for much of my adult life. Stick with the other trusted brands. These are performance tires, and if you are looking for tires to use on a track, then maybe these are the ones for you. If you plan on using them for everyday driving then I caution you to stay away!!!!
