I am just about to order wheels and tires for my 48 chev 2 door sedan and want to make sure I have it right. 15x7 OE chrome wheels on the back with 215/75r15 diamond back wide whites. 15x6 fronts on 205/70r15. My thoughts are that the 7'' wide rear wheels will give it the slightly wider look and the front tire diameter will be about 1.5'' less. Any thoughts or opinions on this setup? Thanks.
