If the maximum weight per tire does not exceed 500 pounds per inch of tire width, an axle may be equipped with tires that have a width of more than 14 inches.
(e) Except as otherwise provided in subsection 2, the maximum overall gross weight on any group of two or more consecutive axles does not exceed the values set forth in the following formula: W=500 [LN/(N-1) + 12N + 36] wherein:
(1) W equals the maximum load in pounds carried on any group of two or more consecutive axles computed to the nearest 500 pounds;
(2) L equals the distance in feet between the extremes of any group of two or more consecutive axles; and
(3) N equals the number of axles in the group under consideration.
2. Two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each if the distance between the first and last axles of the consecutive sets of axles is 36 feet or more.
