You can run a 315 on the stock C5 Z06 rear wheel and a up to a 275 on the fronts with no issues .
I run a 305/19/35 on my CCW's
Will look killer Mr. HowieC5
Thanks Manny! I didnt even bother to look at the other board I am also a member of till after I got some advise from this site. The pic in my earlier post has the 315s rear and the 275s front,seems to look great! Any deals on tires floating around? Brand or speed rating is not too important to me as I dont track the car and I prolly havent gone faster than 140k in a few years. However I would like the tire to have a longer tread wear rating. Cheers Howie
Outside of wishing to stay in Canada and support Canadian businesses, I have heard that the tire rack has great deals. You may want to check them out and compare them against other places. Costco has no problems mounting tires that are not purchased at their store.
Yeee...I feel dirty for posting that.
