Light truck tires, those designated with a LT in front of the tire size, use a letter rating to designate the load capacity of the tire. The most common light truck tire load ranges are C, D and E.


A light truck tire load capacity is dependent on the size plus the load rating. All tires of a specific size and load range will have the same maximum load capacity. For example, LT245/75R16 tires have a load capacity of 2,205 lbs. for load range C and 2,623 lbs. for load range D.
