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.

I have purchased hundreds of sets of tires over the years... from winter tires to work tires for our vans to race track slicks... nothing beats Michellin... hands down. Michellin tires are always the smoothest ride, best traction and longest lasting tires... and I've tried most other brands. I would only buy Michellin's no matter what vehicle I have. The BEST!

I’m extremely disappointed with the durability of my Michelin tires. I purchased them just about a month ago, expecting the quality and reliability the brand is known for. Unfortunately, after a very normal driving experience, one of my tires already has noticeable sidewall damage. This was not due to reckless driving, but from a common road condition that any tire should reasonably withstand. For a premium-priced tire, I expected much better durability and resilience. It’s frustrating to invest in a trusted brand only to experience damage so quickly after purchase. Tires are supposed to provide safety and peace of mind, and right now, I’m feeling the opposite. I am hoping Michelin will stand behind their product and consider a replacement or some form of support, as this experience does not reflect the quality I believed I was paying for.

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!

I am 66 years old and have been buying Michelin tires since i was in my 30 s excellent tires even better now that they last longer .You can find cheaper tires,but i do a lot of high performance driving in dry and wet very good sence of security excellent road feel,I believe them to be the best and honestly believe you get what you pay for.

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.

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.

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.

Absolutely disappointing product and quality . Bought a car that came with these underperforming overpriced tires that were installed at 12,500 miles on an audi s5 at just 22,500 miles 2 of these tires blew up on me on the road as i was driving 35mph and the other 2 they’re already down to about 5/32 thread life i hear these are warranted until 45k miles but ill be lucky to get 7k miles out of the two that are left honestly will never be purchasing from this brand as they like to mark up their prices based on their brand prestige but they really fall short of what they are giving their customers. I would honestly recommend to people considering buying this tire to go with a cheaper alternative like a yokohama or continental as they arent perfect either but atleast you wont break your wallet by overpaying for a tire that can easily explode and wear out like the michellin ps4 ‘s . Never again will i use Michelin products not even for free i honestly don’t see the justification for the price of this tire especially since lots of customers constantly report that these

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.
