Ariz. Admin. Code tit. 17, ch. 6, art. 4, tbl. 3.01 - Maximum Permitted Weight Computations for Overweight Axle Groups - Axle Width 8 Feet 0 Inches

Maximum allowable axle group weights determined by using the computation formula: Weight = 1.5 X 700 (L + 40), where:
L = Distance between the center of the front axle and the center of the rear axle of any group of axles within a space of 3' 5" to 18' 0".

Legend (Tire measurement excludes any load-induced tire bulge):

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

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