Trailer Tire Load Range Chart

Trailer Tire Load Range Chart

The load range is the load capacity of the trailer tire. A tire’s load range is located on the sidewall of the tire. The load range is rated with a single letter, such as B, C, D, etc. If you have two tires of the same size but one with a load range of B and D, the D range tire will have a higher weight capacity.

What’s better load range D or E?

The load index determines how much weight per tire you can handle. D and E is the load range meaning that the D is 8 ply rated with a max psi of 65 and E is 10 ply rated with a max pressure of 80 psi. Like mentioned above, E is better for towing because you can fill the tire with more air pressure.

What is the difference between 5.30 and 4.80 in a trailer tire?

Expert Reply: It’s fine to use a radial-type tire as a spare (a tire with “r” in its size code) with a trailer that has Bias ply “d” tires but for a short distance in the event of a flat tire. But mixing tires is not recommended for everyday use because their internal construction is different.

What does load range D mean on trailer tires?

The D load range is rated for 2,540 pounds at 65 psi. And the E load range is rated for 2,830 pounds at 80 psi. If you had a single axle trailer with a gross weight rating of 5,000 pounds, you would use the D or E tires in this size since the C tires would be under rated for the weight.

What load range is 10 ply?

For example, an “E” load range indicates that a tire is equivalent to a 10-ply construction tire.

What does the D stand for on trailer tires?

What does load range 112 mean?

The numeric load index code 112 represents the maximum load carrying capacity for single wheel use and 109 represents maximum load carrying capacity for the dual wheel use. The first number 112 denotes a tire’s ability to carry approximately 2,470 lb (1120 kg).

How tall are 530 x12 tires?

What is a better trailer tire bias or radial?

The vehicle in the front does all the fancy work, while the trailer in the back mostly just rolls forward. Radial tires, however, do perform better than bias tires, and that performance is quickly noticeable. The ride is smoother, the trailer does not bounce and sway as much, and radial tires have a longer life.

What does the 5.30 mean on a trailer tire?

Expert Reply: 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 22-inches in overall diameter.

What’s the difference between R15 and D15?

Can you run bias ply and radial on a trailer?

Bias-ply trailer tires

No matter which type of trailer tire you choose – radial or bias-ply – make sure you don’t mix them on your trailer. Since their internal construction is so different, each type performs differently, and combining them can negatively affect your trailer’s ride quality and the tires’ life.
