80s Caprice wheels offset

[Bob Ash]

What is the lowest wheel offset I can use without tires (circa 235/70) rubbing whe wheel wells?

[MrBrown]

I have an 84 capeice W/ stock wheels and 235/70's fit with no problem.

the sidewalls on 235/70 tires will be huge.
use 235/65/15 instead. that will be the same size as stock.

as for rubbing, you can go pretty huge on the rear before you have problems, and up to around 255 on the front
