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.

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.

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.

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.

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.

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.

Unfortunately, I cannot recommend these tires. This review comes after driving 50,000kms, city and long distance highway driving in an AWD vehicle. Tire size is 265/40R/21. Maybe this tire is not ultimately suitable for a low profile vehicle, I'm not sure. As I often read reviews before making a purchase, and I did before purchasing this tire, I feel compelled to write a review with my experience. In my opinion, this tire lacks stability and handling ability. They've always felt slippery in rain and though the first year was somewhat bearable in snow, since then they've been poor. On dry surface they roll into (vs. over) any groove in the road (think crack in the road that has been filled with tar); the tires feel like they are sinking into the tar. They've never felt like they have enough air, though I've repeatedly checked the level. Today, I felt like I was 'skating' while driving in 2cm of snow. No traction whatsoever. I have always put Michelin tires on my cars and have always been happy with them. Sadly, that hasn't been the case with this one. I will consider another Michelin tire, I just can't recommend this one.

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.

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.

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.
