Question:

Dear Etrailer Representative: I have a 1960 single axle Airstream Safari for which I need 2 new tires. A tire company here sold me I can return them 2 Taskmaster Contender ST205/90D15 tires, which seem too small to me. They measure about: UNMOUNTED OD 28 3/4, ID 15 1/4inch with 5 1/4inch wide tread. The original Cooper Super Road-Master Nylon 7.00-15LT Tube Type Load Range D 8 Ply Rating Tread 6 Plies Nylon Cord measures approximately: MOUNTED OD 29 1/2inch with 6inch wide tread body bulges another 2 1/2inch for total width of of 8 1/2 On a Rim with OD 16 1/2inch with 7inch width as best as I can measure. Legible numbers printed on rim/wheel are 15 x 6 2160 lbs Max 60 What is the best/right tire I need? Thank you in advance for your assistance. Sincerely,

The reason you tire looks small is because it isn't mounted to the wheel and inflated. The closest comparable match to your 7.00-15LT tires is going to be a 225/75R15 like the Castle Rock ST225/75R15 Radial Trailer Tire - Load Range D # 274-000029. It's going to an inch shorter in overall diameter.
