I just bought a modded out camaro with stock 16 inch wheels, the nitto tires are about gone. I would be using it as a daily driver, but this car pushes about 420 hp, so I would like some traction and stability at high speeds. Later on I will be getting 18's that are 10 inches wide. For what I would be using it for is there much of a difference between y and z rated tires? Thanks for the opinions guys.

 

I found a tire by Avon Tech that has all very positive reviews for grip and handling. Does anyone think otherwise. Price isn't bad either.

 

have you been to tirerack.com or discountire.com?

 

check tirerack.com
i have kumhos (89 a piece or so, pretty cheap) and they're decent i suppose
o, and i believe y is rated for up to 149mph, and z is 149+
not much of a difference, and i hope you don't maintain that speed a lot anyways, for all of our sakes

 

Z was at the top of the old system, means speeds in excess of 149 mph.
W & Y have been introduced recently, W is up to 168 and Y is up to 186. There is also V, which is up to 149 I believe. Anyway, W & Y tires are also referred to as Z tires a lot of the time. The tire rack has a good writeup on this that can explain a lot better than I can. I wouldn't worry much about that though. Just keep your eyes glued to the dry traction rating or else you'll be disappointed, especially with a big hp jump over stock.
