When airing up the Kenda K353 Bias Trailer Tire # AM10066, the tire is designed to be inflated to the 80 psi when the weather is colder. The tire can handle the increased pressure that comes with they heat up during driving. The only way it would get to hot is if you exceed the speed rating for the tire.

The Kenda Tire # AM10066 has a speed rating of 65 MPH. It has a load range C with a ply rating of 6 and has a maximum load capacity of 1,045 pounds at 80 psi.

Answer 5

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…

Answer 6

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…

Answer 9

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.

Answer 11

I have never heard of a 6.00-12 tire but theoretically yes, you can use the same 12" rim for a 5.30-12 size tire like part #AM10066 as the last set of numbers refers to the wheel size that the tire fits. You do need to make sure that your tire…

Answer 12

A trailer will always be limited to the weakest components. I can't speak about your trailer specifically but the 4.80-12 tires can hold up to 990 lbs for class c. This does not account for the carrying capacity but if you subtract the weight of…
