| View Full Version : How common are the "Z" speed rated NorthStar's Lawrence 03-19-04, 01:43 PM Just Curious. BeelzeBob 03-19-04, 02:18 PM Just Curious. To my recollection all the 93 and 94 STS's were built with Z-rated tires. In fact I think that even 95's had Z rated tires . I believe that the Z-rated tires were an option first in 96.... Only the STS/ETC got the z-rated tires. The standard Seville, Eldorado and Deville got lower speed rated tires and the appropriate speed limit in the PCM for the tires. | |
