can anyone tell me the largest tire size i can put on rear axle 1968 camaro ss,multi-leaf springs, 8.5 inch wheel with 4.5 inch offset without modifying my wheel wells. thanks

you can look it up and see the different hights and widths for all their tires
my guess is 275

275/60/15 unless your plus sizing.

28" tall and 10.8" wide

A '67/'68 car can run a 9.50/14, mud&snow using 14" x 6" w/ 3.75" b/s stock steel painted rims, but you have to raise the rear up about 4" to be able to keep it from rubbing b/c it completely fills the upper half of the wheelwell!

This tire is about 29.5" tall!!

My car had a finger's width front and back when I had them on my car. And at 70mph by my speedometer, I was clocked at 82 one night speeding!
