Customer Reviews
I run the Michelin Pilot 4S on my Porsche GT3 and my Cayman S. I use Pilot all season 4S on my 1979 Porsche 930. I drive all three cars up at Atlanta Motorsports Park on the track as I’m a member and a driving instructor there. These tires handle amazing in wet or dry conditions and in my opinion are the best tire Michelin has developed in a long time. I look at all of the various sports cars on pit lane and I would have to say 60-70% are using this tire. Discount Tire did an amazing job mounting and balancing them when I purchased them from them and their pricing and level of customer service was top notch. I will continue to use Discount Tire for all of my future tire needs.
My PS2's from day one were bad at tramlining. All suspenion parts are in perfect condition. The PS2's were 5 years old and became slippery as they aged. These new tires are grippy and smooth on rutted roadways. Glad I got them.
Great tires I have same set on another car
