i didn't think you could fit any tires that big under a b-body without modification...interesting.

on a 68-70 plymouth b-body you can go with a 15" diameter, 10" wide wheel with a 275/60/15 tire? i have 15" diameter, 8" wide wheel with the same size tire. i wasn't sure of the backspacing, but it is good to know that 5 1/2" is good for a 10" wide wheel. what would be good backspacing for an 8" wheel? 4 1/2"?

what is the proper backspacing for the front tires? i would like to put 15" diameter 7" wide wheel. i was hoping to use regular wheels in the front and reversed in the back, for a nostalgic look.

front:



rear:



would 3 5/8" backspace be too much in the front on a 15" x 7" wheel?
