Simplify Your Oversize/Overweight Loads
A vehicle may be operated or moved upon any public highway if:
Except for a steering axle and axles that weigh less than 10,000 pounds, each axle has at least four tires if the tire width of each tire on the axle is less than or equal to 14 inches. 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.
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 = 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. As used in this section, “tire width” means the width set by the manufacturer of the tire and inscribed on the sidewall of the tire.
