was wondering what is the biggest 15 inch weld wheel i can get under my rear wheel wells?you know backspace etc.i see some pics of some 68 and 69's with some big tires in the rear wells.
I just put a set of 7x15s by wheels vintique on my '67 GS. They had a 4 1/2" backspaceing and with a set of 235s with a 60 profile, they were a little tight and required a bit of fender modification. A 15x7 with a 4" backspaceing would have been a bolt on. Buick made them with the 4" back spaceing.
