Anybody know what is the biggest tire I can run in the rear of a 69 Dart using 15X7 with 4in Back Space? Looking to run BFG Radial T/A's
Are you running small bolt pattern original axles? Including original axle re-drilled for LBP?
OR aftermarket or shortened large bolt pattern axles?
With small bolt original axles, I've run 4.25" backspace rallyes with 245/60/15 on my 68 Dart. Close on inside and outside with a very low leaf spring worn out rear end.
LBP aftermarket/shortened axles move the axle flange out 1/4" or so. Then you will need 4.5 backspacing.
