Great tires, however contact patch seems to be narrower than previous generations and doesn’t look as wide and aggressive as previous. But performance/comfort/noise wise, best tires out there

After 85 days, this tire took on a flathead bolt. The picture does not make sense. My local tire repair center patched the tire; however, I am alert for further problems.

On my Porsche 2003 c4s I purchased 4 ea Pilot Sport 4s and the car runs & tracks beautiful also eliminated a lot of the Road noise I had from Previous "FALCON" tires

Absolutely the best tires I've ever had. I have pushed them to the limit and can not believe they hold the road like they do. A great road tire as the ride quality is amazing also. You feel the road but no discomfort.

Good for summer/wet weather, but you should NOT use these in the extreme cold winter months we see in the Midwest. The rubber compound in these tires will harden and, potentially, crack.

Like all Michelin tires that I have purchased, they meet expectations. Sport Pilot AT 4S Installed on my 2012 Honda Accord they are quiet and drive true. On the Honda I don't require the performance I demand from Sport Pilots Michelins on Carrara.

PS4S on my 911 seem to be performing well. Quieter, with good grip in the dry. Haven't had the opportunity to try wet roads. Consider these tires for your 911.

These were the original tires that came with my Mercedes GLE53 AMG Coupe. I have about 15000 miles on them but I'm see the following issues in the sidewall of the front tires. Not sure if it's wear issue or something else...

One of the best performance tires out there, cornering grip is extraordinary. Remember you are not buying these tires for longevity, you are buying them for performance.

Have driven for one season on these tires. Love the way they roll and track true so you aren’t correcting the steering like so many other brands. A little more tire noise than the x-ice tires but excellent handelling.
