LEGAL LIMITATIONS

WEIGHT

MAXIMUM LEGAL WEIGHT ALLOWED

A vehicle may be operated or moved upon any public highway if:

The maximum gross weight does not exceed 80,000 POUNDS;

(a) The maximum weight on any SINGLE axle does not exceed 20,000 pounds.

(b) The maximum weight on any TANDEM axle does not exceed 34,000 pounds.

(c) 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.

(d) 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.

(e) 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:

W equals the maximum load in pounds carried on any group of two or more consecutive axles computed to the nearest 500 pounds;

L equals the distance in feet between the extremes of any group of two or more consecutive axles; and

N equals 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.

TANDEM Axles 60,000 POUNDS maximum – purple weight chart

Example: 8' - 0" Distance Between First and Last Axle in Feet

4 tires, 8' - 0" Wide Purple Load = 1.5 x 700 (L + 40) 8 tires, 8' - 0" Wide Purple Load (+ 15%) = 1.15 x 1.5 x 700 (L + 40) 8 tires, 10' - 0" Wide Purple Load (+ 25%) = 1.25 x 1.5 x 700 (L + 40)

TANDEM Axles 52,000 POUNDS maximum – green weight chart

Example: 8' - 0" Distance Between First and Last Axle in Feet

4 tires, 8' - 0" Wide Green Load = 1.3 x 700 (L + 40) 8 tires, 8' - 0" Wide Green Load (+ 15%) = 1.15 x 1.3 x 700 (L + 40) 8 tires, 10' - 0" Wide Green Load (+ 25%) = 1.25 x 1.3 x 700 (L + 40)

Weight: * (5 axles) * (6 axles) * (7 axles) *Depends on spacings

  • Single – 20,000*
  • Tandem – 46,725*
  • Tridem – 58,000 to 59,000*

*Depends on spacings

Note: 58,000-59,000 pounds is the tridem “bonus weight” in Nevada and is now allowed on one or two tridems. Additional tridems would get around 51,000 pounds. A Tridem drive on a tractor can be permitted for the bonus weight (as one of the two tridems) as long as the spacing from the steer axle to center of middle drive axles is at least 18 feet. Loads in excess of these dimensions are reviewed on individual basis only.
