Overweight Divisible Load Provisions

TIRE WIDTH

In circumstances where weight limitations are based on tire width, the manufacturer’s size, as indicated on the sidewall will be used to determine maximum tire width.

Example. Tire sidewall reads: 265 R 22. 265 is the metric width. To convert, multiply 265 by .04 which gives you 10.6. Your tire would be 10.6 inches wide.

OVERWEIGHT DIVISIBLE LOADS

Utah Administrative Code R909-2-21

The division may issue an overweight divisible load permit to a motor carrier for moving a vehicle or combination of vehicles and loads exceeding the legal limits if the requirements of this section are met:

  • The vehicle or combination of vehicles is properly registered for 78,001 to 80,000 pounds.
  • The width of the vehicle does not exceed 8 feet 6 inches wide or 14 feet 6 inches high.
  • Configurations equipped with tires 11 inches wide or less will be allowed 450 pounds per inch of tire width.
  • Configurations equipped with tires 11 inches wide or greater will be allowed 500 pounds per inch of tire width.
  • Axles weighing more than 11,000 pounds are required to have at least four tires per axle unless the axle is a steering axle, a self-steering variable load suspension or retractable axle, or a wide-based single tire that is 14 inches wide or greater as indicated by the manufacturer rating on the sidewall of the tire.

    The combination unit will conform to the bridge formula and the legal axle and gross vehicle weight limits.

    A divisible load permit may not be used to transport a non-divisible load except when the non-divisible load meets the divisible bridge formula and divisible size limits specified on the permit.
