My trailer is equipped with ST175/80D13 tires which I need to replace. I cannot find any locally and the shipping cost is almost as much as another tire if I buy them online. Wally World carries a 5.3/12 with the same bolt pattern. Would these work? Boat is a 14 ft. Glasstream with 48 HP Johnson. Total weight is under 1000lbs. Thanx for your imput.
