I have a 1965 and am going to do a power disk brake upgrade and need to upgrade to a 15x7 wheel. It has 14x7 on it now and I want to do a 15x7 front and 15x8 rear. Does anyone have this setup on a 65 and would I have problems with tire clearance? Also what tire size would you recommend for the 15x7/15x8? Would a 1 inch width differance make a big differance or should I just stick with the 15x7 on all 4 corners? Thanks in advance.
