   Which back space works the best for that wheel/tire combo at all 4 corners? A 4.5 or 5 inck back space? The car is a 70 GS.

   I have 15x8 Buick rallies with 4.5 inch backspace using 255/60/15 tires on the rear of my '72 Skylark and they fit very nicely.

   4.5" back space for an 8" wheel. For the 10" wheel, 5 1/2 - 5 5/8" works best. That is for the 70-72.
