Here are the rims I put on my blazer, white letters out. 225/60r15 front, 245/60r15 rear. It is lowered a bit so they fill the wheel well nicely. 10" back, 8" front. Would have to take them off to figure the offset, but originally mocked a tire size piece of signboard , then attached a piece width wise so I could check different widths clearances. Once I calculated widest tire I could fit and still be flush with fender lip, then measured that for my offset.

This is gap on rear tire and springs, enough for hard cornering to still clear.
