I posted a response to the OP's same question on the FFR forum so nothing new here for him. Here is a picture of 255-60/15 on 9-1/2 rims and 215-70/15 on 7-1/2 rims. The installer had absolutely no quams about mounting them and I think they looks fine since this is a street roadster replica and I needed the clearance for 2-1/2 in exhaust pipes.
