Tyre sidewall markings?

peking97 · 2010-02-09 20:54:34

I've checked several websites but still cannot find what the *Z* signifies in the following sidewall marking:- 215/50/ZR17/95W I can find info on all the other markings just not the Z. Any info appreciated.

here ya go fella (stolen from another webiste)

Before 1991 a ZR meant that it was rated for a high rate of speed since the Z indicated the speed rating. After 1991 the speed rating was moved to the end of the code, but many manufacturers still include the Z combined with the R in their high performance tires.

as above ignore the Z, the 95W is the bit you should pay attention to.
