Expert Reply:

Trailer tires are organized by Load Ranges which basically represents the weight capacity for that tire size. So for example the Load Range C trailer tire and wheel part # AM32395 that you referenced has a weight capacity of 1,820 lbs at 50 psi. Different tire sizes would have different capacities at the same Load Range.

Answer 1

Differences in Load Ranges mean different weight capacities for the tire. In the tire size of 235/85-16 that you referenced a Load Range F means 3,960-lb maximum load at 110 psi capacity and Load Range G means 4,080-lb max load at 95 psi. Kenda is…

You could do the Kenda #AM30660 and safely pull at 65 mph. This is our only option for a pre-mounted tire and wheel combo. I strongly recommend going with a tire with a higher speed rating, but to do this they will not come mounted on the wheel. You…

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…

To measure the width of a trailer wheel you will measure from where the tire beads will seat on the wheel. That will be from the inside of the inner wheel flange to the inside of the outer wheel flange, not from edge to edge of the wheel. To measure…

Answer 5

Speed is a huge issue with trailer tires actually. Unless otherwise noted trailer tires are rated as 65 miles per hour as their max speed. Exceeding the speed rating will cause the tire to heat up and fail easier. We do have a couple brands that have…

Answer 6

For that size tire, 4.80 X 8, I recommend the Kenda tire, #AM10004. This tire has the Load C rating and fits the 8 inch x 3-3/4 inch rim. Using the heavier load range could extend the life of this tire. The Kenda tire is a bias tire that tend to run…

It depends on how much clearance you currently have around your wheels. Ideally, you should have 3 inches minimum clearance between your fender and your wheels and an inch minimum between your sidewall and trailer frame/wall. As your wheel size…

Answer 9

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…

Answer 10

The speed rating limitation for a trailer will come down to the tires, it has little to nothing to do with the axle, hub, or wheel size. That said, smaller tires generally do have lower speed ratings but you do not need to upgrade the wheels on your…

Answer 12

The difference between the tire diameter you'd have now and a 14 or 15 inch trailer tire size would be about 6 inches. This would take up about 3 inches of your current fender to tire clearance so you'd need to make sure that wouldn't be…
