I want to put 275/40/17 Nittos on the back of my 87 Notch but my current Centerline Billet wheels are 8" wide with a 5" backspacing. If I get extra wheels that match but are wider, I have to go with a 9.5" wide wheel with a 6" backspacing. Will that work, or should I just bite the bullet and put the tires on the 8" wide rims (not the best combo)?
