I have about 1,500 miles on these tires that I bought new. However, on one of the tires are two, approximate 1” vertical bulges protruding outward. Is this normal? Great looking/handling tires, other than the defects.

I have had to buy 3 of these tires during the first year of ownership of my brand new car. They are expensive and nails, pot holes, bumps, etc, pop them very easy and they wear pretty quick from normal driving. I don't go to the track.

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.

I am a diehard Michelin owner. So my expectation of quality is paramount and that's why I continue to purchase this brand. Excellent ride and quiet for road noise.

Had new PZero on the C4 GTS I bought and almost immediately, LOUD AS HELL…. Even though I’ve only driven about 150 miles, feel so much better and… QUIETER..!!!

I just replaced my Pirelli tires with these Sports on my 2018 Mustang Convertible. WOW, so much quieter and feel like they grip much better. i live in south FL so we have a lot of rain and i feel safer with these pilot sports on my car.

The P Zeroes on my McLaren 720S were way too slippery - minimal grip especially when cold so… I had some “sideways moments with them” (unexpectably!). The Michelin P4S has cured the “problems” - great tire!

I bought these for track days and they work great on track ,only thing my car weights a little more than the sidewalls can handle, the grip wet and dry is awesome ,I graduated them to street duty and the comfort is extrodenary

The summer with these tires has been good, however the wear is not as expected. I will probably only get another summer out of these tires. The soft compound wears very quickly in this application.

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.
