ok, now that i got ur attention. im wondering whats the widest tires i can run on my stock 91 z28. i just wanna see if i can go any wider with out worrying about clearance or any issues.. thanks.

 

i have a 1984 camaro, i think its the same body style. i have 275/50/15 on the rear right now. they are 10.83 inches wide and 26 inches tall. only prob i've seen is under fast cornering and hitting a bump on the outside tire it rubbed a little on the top of the fenderwell on the very outside of the tire. same thing with a heavy load in the car.

 

the current tire size i have is 295 50r 15's on teh back. and 265's on teh front. thay are about 11 inches wide and i also had the same problem as bluebomb, but to fix that problem, you can buy airshocks out of a JCwhitney for 50 bucks i thinka pair. you simply fill them up like a bicycle, teh same type of nozzel, and get the height you need.
