Hey guys I run 275/60/15 tires on my 79 nova. With my new powerhouse motor getting built Im wondering if I can gain some more contact area with a larger rim. I have 15 x 8 with 4.5'' backspacing weld prostars and wondering if I can fit a 15 x 10 rim and run the 275/60/15 on that rim. Alot of x275 guys do this, so im not questioning if that tire will work on the rim, but if the whole package will fit ok on my car? not positive where id want to be on backspacing as well. Perhaps I need to measure it up when the time comes but wondering if maybe someone else has already got it figured out. I rolled the wheel lips already. Im not sure if this wider rim poses a clearance issue or not??
