"W" is a Z rated tire. "W" is just a sub category of the Z rating.westell said:I drove Fbods (Z28 & SS) for thirteen years and tried everyone's Z rated rubba
KDWS we among the worst and I don't care for them on the GTO
This Cooper tire was the last set on my 02 SS, and even though it's only "W" rated, it was better than several Z rated I had, and I'll be putting a set on the GTO next.
Grip, Road Noise, Wet Traction all excellent from experience
I agree on goodyears better, but not by too much, they wore quickly and i had 4 of 8 go bad at seperate times.Tom said:I am no fan of goodyear, but i think they are better than the KDWs on the GTO.
We have to see what Groucho puts on his car with his new long commute, and how much better they are.
