[dougs68ss]

im changing my car to go a different direction, dumping the 15'' centerlines to 17'' tire and rim combo . iam partial to the bonspeeds ,but they come in only 17x 10 . i know from the forum that 17x9 1/2 with 5.5bs is the usual but can i squeeze a 10'' back there with 5.75 bs? with a285x40x17 ? rolled lip for sure. anyone whos tried this? ...doug
