255/60/15 - stock 70-72 Dart

My dart is all stock wheelwells and spring location. I run the CalTracs bars and mono leaf suspension set at 1" lower than stock height, Moser axels drilled to fit both 4"and4.5" bolt circles the stock 10" a-body drum brakes, with Weld Rodlite wheels 15x7 4.5 back spacing and 255-60-15 m/t dragradials. This wheel tire combo has never rubed even with four 200+ pound guys in the car.
