The gross weight on any one axle of a vehicle, or of a combination of vehicles, operated on the highways of this state, shall not exceed twenty thousand pounds on an axle equipped with pneumatic tires, and shall not exceed fourteen thousand pounds on an axle equipped with solid rubber tires. The gross weight on any tandem axle of a vehicle, or any combination of vehicles, shall not exceed thirty-four thousand pounds on an axle equipped with pneumatic tires. This subsection does not apply to implements of husbandry.
3. Notwithstanding other provisions of this chapter to the contrary, indivisible loads operating under the permit requirements of sections 321E.7, 321E.8, 321E.9, and 321E.29A shall be allowed a maximum of twenty thousand pounds per axle.
