I have a set of 15x6 Buick Riviera rally wheels from a 1971 - 1978 Riviera. Those wheels have a 3-7/8" backspacing. I have a new set of 225/75R15 tires on the OE aluminum wheels on my '94 RMW. The OE wheels have a 4-1/4" backspacing. What issues, if any, will I run into if I mount the Riviera Rally wheels on the RMW?
Thanks for any input / advice,
Ed
