The next size up from the 5.30 x 12 tires you have now is going to be a ST175/80-13 size tire. This tire size will have an overall diameter of 24 inches and a width of 6.9 inches. This is compared to the 21.9 inch diameter and 5.6 inch width of your existing 5.30-12 tires, which means that the top of the tire will be about 1 inch closer to the underside of your fender and about 0.65 inches closer to the trailer frame.

For this increase in size, I recommend the Provider ST175/80R13 Radial Trailer Tire w/ 13" White Spoke Wheel - 5 on 4-1/2 - LR C item # TA43RR. This radial tire with automotive-grade tread has a 6-ply rating and a 1,360-lb max load at 50 psi. The 13" x 4-1/2" Steel wheel has a 5 on 4-1/2 bolt pattern and rust-resistant 3-step powder coat.

You will want to make sure you have 3" of space between your fender and tire. If your axles are above your leaf springs you can always use an axle flip kit to gain 2"-3" of lift depending on how thick your axle is. If you have a 2-3/8" axle you will want the Dexter Trailer Springs Over-Under Conversion Kit item # K71-384-00. If you have a 3" axle you will want the Dexter Trailer Springs Over-Under Conversion Kit item # K71-385-00.
