Bridgestone Potenza S01

I had several sets of these tires in Porsche OEM N-Spec. They are noisy and uncomfortable. So what? Porsche themselves required that if a car was ordered with these tires and sport suspension that the order had to be confirmed to make sure that there hadn't been a mistake.

This is a sad reflection upon the sort of people who bought Porsche 928 cars new. The combination of Bridgestone S-01 tires and Sport Suspension is what driving a Porsche is all about. The faster you go the better it gets!

They are a WONDERFUL driving tire. Fabulous grip, amazing turn-in and absolutely predictable at the limit. I found myself anticipating an amount of understeer which had been present in all the other tires I had used, This was replaced by wonderful bite and turn-in with the S-01 (Porsche N Spec.)

The Porsche 928 S4 calls of 44 PSI in the rear tires which causes some tires to wear in the middle and become useless in the wet. These tires are simply the best I ever had on my Porsche 928 in 200,000 miles of driving. If you want to drive like grandma get something else, but if you want to use the car as intended and drive it really hard these are very, very good tires. Sharp response, wonderful feel, and very well-behaved.
