Computation Formula: Weight = 1.5 X 700 ( L + 40 )

(L = Distance between the center of the front axle and the center of the rear axle of a given group.)

Legend:

Line A: Four tires per axle or two 14-inch wide tires. Value is the formula weight only.

Line B: Eight tires per axle or four 14-inch wide tires. Value is the formula weight plus 15%.
