Factory wheels

Demons, Dusters and Dart Sports seem to naturally 'crave' wider tires in rear, due to car's shape and stance. Just keep diameters equal if possible, and that would mean 70-series in front and 60's in rear. Swingers, Valiants and Scamps look better with all four wheels as same size; width and diameter (IMHO) - good also for those of us who like to rotate wheels. Putting 15" or taller wheels (on A-bodies) can lose any semblance to originality mighty quick - more often than not- (especially with SBP - 7/16" studs!)
