Z3 Tires

bmwz3 · Jun 21, 2004

I bought some new Bridgestone Potenzas S03 for my Z3 about a month ago. The rears are 255 / 35 18 inch.

Anyway, I think the original stock Pirelli's 7000's are better tires. From what I read about these Bridestone's these are supposed to be great tires. I just don't get it thou, they don't grip as well and are loud.

Can some tire guru tell me if I am crazy or not? [:p]

I do not know about your situation, however I have heard that the Bridgestone S03's are great tires. I have never used them. I have used Toyo Proxes, love them, Michelin Sports, no tread life and too expensive, and Kuhmo Estca's. These are good tires, cheap and long lasting tread. I would say that as far as grip they have the least. The lower the tread wear index the "gripper" the tire, at least in theroy. Noise is created by tread design, are the S03's "luggy"?

Check your tires for proper inflation. The best tires in the world will not grip if improperly inflated. I find that I need to use a slightly less than recommended tire pressure than the car placard recommends, or my tires especially the rears will wear out prematurely down the middle. One must also take into account the accuracy or (lack of) when considering tire pressure. It might be my pressure is dead on the car placard recommendations but my gauge reads a little high. I run a chalk line across the tread and then roll the tire and check the wear pattern of the chalk line. Inflate or deflate per wear pattern and then start all over again until it's right. Then I record the tire pressure of each tire with the same guage and just keep em inflated using the same guage. I get the longest tire life, and best possible traction each tire can give, when doing this procedure. It takes a little time to do it right at first but then it's always spot on for the rest of the life of the tire. [whip]
