what is load range on tires
All tires, including trailer tires, have load ranges. These are marked on the sidewall of the tire, and range from the lightest weight the tire can carry (load range B) to the heaviest (load range E). The load range is a measure of the maximum capacity an individual tire can carry for a boat or trailer. Most boat trailers have a load range of B, C, or D. Tires with a load range of C can carry 1,820 pounds. On a single-axle trailer, both the tires can carry a total of 3,640 pounds.
