The Kenda Trailer Tire with Galvanized Wheel # AM30630 is a bias tire which has cords inside which run at a 32 degree angle to the direction of travel for a stiffer sidewall than a radial tire. This tire has the standard speed rating of 65 mph. I've added a link to a video review of this wheel/tire combo for you to take a look at.

We do no have pre-mounted wheel and tire combo that is the same as # AM30630 - size 4.80-12 with a 4 on 4 bolt pattern and load range C - with a higher speed rating, however, you could purchase the tire and wheel separately and have them mounted at a local shop. For the tire, you would want the Taskmaster # TTWSF48012C, which is rated for a maximum speed of 81 mph. This tire, like each that we carry, is tubeless. Then for a wheel, you could use the Dexstar Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - White Powder Coat Item # AM20122 I've added a link to a video review of this product for you to take a look at.

The two tire sizes you referenced, 4.80-12 and 5.30-12, both fit 4-inch wide rims, but they differ in their overall diameter. A 4.80-12 tire/wheel when fully inflated will have a diameter of 20-1/2-inches while the 5.30-12 size will be just under…

Trailer tires should always be inflated to their max psi rating so that you ensure that you get the full weight capacity and best tire wear characteristics. For example, the part #AM30630 that you referenced should be inflated to 90 psi to get…

Answer 5

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Answer 6

The main differences between the two trailer tire sizes you referenced are the outer diameter for the two and the capacities available. For the 4.80-12 tires they are 20.5 inches in overall diameter and have 785 and 990 lb capacities available. For…

Answer 7

The 90psi is going to be the cold filling pressure; as you drive, the tires are going to heat up and the air inside them is going to expand. When running long distances, most tire manufacturers recommend that you stop for 30 minutes for every 3 hours…

Answer 8

I have two options for you, but both of them have load range C tires. C is going to be the highest you will find for a 4.80-12 tire, and in this case gives you a maximum load of 990 lbs at 90 psi. We have the following: -Kenda 4.80-12 Bias Trailer…

The answer to your question will depend on if you have hub centric or lug centric wheels. What's the difference? Lug centric wheels use wheel studs embedded in the hub and lug nuts to attach the wheels. The wheel studs provide all the support for…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 11

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 12

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
