Expert Reply:

The wheel you have right now is 4 on 4 bolt pattern with an outer diameter of the tire at 16.1" and a width of 4.7". Kenda 4.80/4.00-8 Bias Trailer Tire with 8" Galvanized Wheel - 4 on 4 - Load Range C Item # AM30050

If you wanted to go up to a 13" 4 on 4 rim with a 175/80-13 tire the outer diameter of the tire would go up to 24.1" and the width would be 6.6. Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel - 4 on 4 - Load Range C Item # AM3S130. Which is a significant increase. You need at least 3" of clearance between the top of the tire and bottom of the fender, if you have a fender, as well as clearance between the frame, suspension components, and the inside of the tire.

If you went with a 10" rim and a tire size 205/65-10 the outer diameter would be 20.4 and the width would be 8.4. Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel - 4 on 4 - Load Range E Item # AM3H460
