The best option we have for the tire size of 5.30-12 would be the Taskmaster tire part # TT53012C. This is a radial like you mentioned which is much better for highway use than a bias-ply.

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

This tire also has a speed rating of 81 mph too.

Answer 1

The psi should be listed on the sidewall of the tire. It is recommended that tires always be inflated to the max psi. The max psi of the tire will depend on the tire's load range, not the weight of the trailer. For instance, we carry 5.30-12…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Answer 7

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The 12 inch tires that we carry are rated for 65 miles per hour. Any faster than that for extended periods and the excessive heat build up will cause tire failure. To get a tire with a higher speed rating you would have to go up in size. That also…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
