I'm completing a disc brake conversion and can no longer run the 14" Magnum 500 wheels.
Since I have to buy new wheels and tires, I'd like to go up to a 17x8 with 235/55/17 tires (or even a bit wider on the back if I can!).
BUT - I'm keeping the skirts on.
Does anyone know what the proper backspacing for 17x8 wheels with the skirt in place would be??? I'm having a booger of a time figuring it out.
Thanks for any advice!
 
I have 275/60/15's with 15x8 wheels, 4" BS on my 66. They fit but they should be 4.5" BS for more skirt clearance.

If I was going to a 17x8 wheel and tire with the same tire width and height, in this case 10" wide, 28" tall, it would still need 4.5" of backspace.
