15 inch steel wheel measurements

OK .... my 215-65-15 should fit on my customer 15X5.5 wheels ... and the rears i will have custom made also by stockton so they will be a gurantee fit and no rubbing ... they can move offset any where .... but not i am glad i can use 15X8 on rears with 255-60-15....Gentleman ... THANK YOU very much for the help and Happy Holidays ...Frank
