Apologies if this has already been covered but I did spend some time searching and did not come up with a definitive answer I am looking to buy a set of staggered 15x7 and 15x8 reproduction chrome rallys for my '66 Skylark. The car has the stock 10 bolt rear-end. Front has a disc brake kit. I like the look of a little less BS and a little more "dish" to the wheel so here is what I am hoping i can run -- Front Wheels -- 15x7 with 4" BS Tires -- BFG Radial TAs 235/50/16 Rear Wheels -- 15x8 with 4.5" BS Tires -- BFG Radial TAs 255/50/16 Can someone please confirm that this setup will work? I am concerned I may need more BackSpacing, particularly in the rear. Many thanks in advance for any advice :TU:
I'm using the 15x7 Buick wheels on a couple of mine. 255/60-15's are very tight on the outside at the fender lip....I can just fit my fingertip in there... it may rub under some conditions. The Buick 15x7's measure 8" outside edge-to-edge. Backspace is 4-3/8" to the outside edge. My blue '66 has a 12 bolt rear which is an inch narrower. That half-inch per side centers the 275/60-15's nicely. So a little more backspace than stock is ideal. To summarize, a 15x7 wheel should have 4-1/2"+ backspace, and a 15x8 wheel should have 5"+ to fit a 255/60-15. A half-inch more should work even better.
