Maximum Legal Weights
Single Axle: 20,000 lb.
Tandem Axle: 34,000 lb.
Maximum Gross Weight: 80,000 lb.
Note: The maximum weight per tire, measured by pounds per inch of tire width, does not exceed 600 pounds per inch for a steering axle and 500 pounds per inch for all other axles.
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]
W = the maximum load in pounds carried on any group of two or more consecutive axles computed to the nearest 500 pounds;
L = the distance in feet between the extremes of any group of two or more consecutive axles; and
N = the number of axles in the group under consideration.
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.
