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!!!!

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.

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.

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.

These tires are outstanding. From road feel to traction and handling they have exceeded my expectations. For street tires I don't think you can do better. The 40F limit of temp is something to consider if you are driving in the mountains.

not a durable tire. 2765 miles on developed a sidewall bubble that meant the entire tire needed to be replaced after michellin attempted to bland road hazard instead of manufact defect and during mechanics showed steal not intact and bubble was close to catastrophic bursting that may have lead to loss of control or accident. not readily available to be replaced been waiting 2 weeks. mechanics verified no road savage curb damage or accident or rim or tire cabbage to support anything but manufacturers defect with less than 0.1 mm tread used. look for better tires.

Michelin pilot sport as 4, tires are amazing. Extremely smooth ride, quiet tire. Very happy. Went with 255/40/17 on front 285/35/18 rear since the OE 265/40/17 front and 295/35/18 was not available. Fits perfectly on factory c5 zo6 wheels. 100% satisfied!

Bought these tires for my "New to Me" 2012 Lexus LS460. Ride improved greatly. These tires are also very quiet. While my car isn't a sports car, it does have a top speed of 150+, so I needed a "Z" speed rating. While it doesn't like to be pushed, the grip does feel more stable. Over all highly impressed with these tires.

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.

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.
