1969 dart gts 440 ...looking to go from a 14" to 15 wheel...I'm looking at the vintage classics...5 X 4 ...they come in 3 different backspacings....4.000
4.225 4.625....anyone know which would be the right application
That 4.225 backspace is the best to fit the most tire and rim. I have 245/60/15 on the rear of my 68 Dart and it just barely fits. Some rubbing on on side under hard corning. And my leaf bushings and leafs are shot.
225/60/15 with 4.225" backspacing will work fine too. I ran those on there also with 15x7 cop car rims with 4.25" backspacing.
