Let’s see those 255 60 15 rears!!!
This picture is a comparison view.
Left side is a 15" X 7" (4 1/4" back space? (Wheel Vintiques Rallye)) wearing a 235/70R15 tire.
Right side is a 14" X 5 1/2" (factory Rallye) wearing a 215/75R14 tire.
I plan to go with 245/60R15 tires (either Cooper Cobra Radial G/Ts or Mastercraft Avenger G/Ts) this spring.
