Match the tire's sidewall size and check valve orientation and hub clearance before ordering, especially on modified wheels. The 12½-inch designation is the nominal tire size, not the rim diameter.
Installation tip: Inspect the tire interior for debris that caused the previous flat. Lightly inflate the tube before fitting, then ensure it is not trapped between the bead and rim. Inflate to the vehicle and tire manufacturer's recommended operating pressure.
