A 5.30-12 trailer tire like the excellent Kenda K353 # AM10066 will be about 0.7 inch wider and 1.2 inches taller than the existing 4.80-12 size tires you currently have mounted. As long as you have the fender and frame clearance available for this slightly larger tire then you can absolutely make this switch. Keep in mind that only half of each of those differences in size will actually affect these clearances.

We recommend having at least 3 inches of clearance between the top of the tire to the fenders to allow for suspension travel and at least 2 inches between the tire sidewall and trailer frame.

This particular Kenda trailer tire features a maximum load of 1,045 pounds at 80 psi. You will be able to use your existing wheels with the new tire.

As a short term solution should you get a flat or blowout you could use a 4.80x12 in place of a 5.30x12. But you will want to get the 5.30x12 fixed or replaced as soon as possible. Having a different size on the trailer can affect capacity, tracking,…

Increasing tire width will not really benefit you in any significant way. You would see a slight increase in stability, but if the trailer already rides pretty straight, you may not see any improvement. The 5.30-12 tires would also make the trailer…

Wheel diameters are not measured using the overall diameter. The are measured for diameter where the tire sits so the diameter is less than the overall diameter of the wheel. With 5.30-12 tires you have 12 inch wheels so tire #AM10066 will fit.

What you could do is go up to the next highest load range. The tire will have a higher capacity and ply rating so it will be more heavy duty and last longer. Please note though that using higher capacity tires will not increase the capacity of the…
