Expert Reply: The load range has to do with the horizontal and sidewall strength of a trailer tire. The C range tires are 6 ply and the D range tires are 8 ply. Because you are operating at half of the spring capacity of your trailer, bumping to a higher load range won’t adding much of a benefit other than giving yourself greater peace of mind.
