Ariz. Admin. Code tit. 17, ch. 6, art. 4, tbl. 3.05 - Maximum Permitted Weight Computations for Overweight Axle Groups - Axle Width 9 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".
