Question along same line for a highboy with no fenders. How do you determine the cross section width or tire bulge of a mounted tire? trying to get to about 1 or 1 1/4" from body. Thinking of buying 8" or 8 1/2"wide 15" wheels and already have a couple of NOS LR60-15 Goodyears. How do you determine the cross section width?

around too long to not know this but don't.
