Discount tire ruined my slicks while taking them off my rims to put on my new Yokohama AVS tires. The slicks were M/T 22x8-15. Anyway, they gave me a pair of new slicks which is **** good considering the old ones were half worn. The new slicks are M/T 26x8.5-15. I plan to put on fender flares because of the offset of my rims and was wondering what type of offset on a 15x7 rim would I need to make these new slicks work? What is the maximum offset that can be run on a 240z? Does anyone run these slicks? Other good news is I just returned from Houston with my new engine and will put it together and in the car this week! Only a few short weeks until my 500+hp motor theory is tested. Thanks for the help.
