From a street perspective;
My stock 68 Barracuda tubs accept 325s with just the springs offset.
IIRC those are 13.6 profile on 10s , but 10s are really not wide enough.
Agreed, you really want the tire on the widest wheel possible, or you are forced to run low tire pressure and you will get more sidewall flex with a narrow wheel, wide tire combo
I run 11.25" wheels with 13.1 section width tires. Just under 2" less than the section width.
