Has anyone ever used 15" rims, which were standard size in the earlier years on a newer XJ that used 16" rims as the standard size? I have a 2000 XJ Classic and have someone looking to get rid of a set of factory aluminum 15" rims with BF Goodrich all-terrain KO's. I wondered if there would be any clearance issues with the smaller rims. I currently have the factory 16" aluminum rims with 225/70-16 tires.
