2505.1The gross weights imposed upon the highway exerted through the wheels on any one axle of a vehicle shall not exceed twenty-one thousand pounds (21,000 lbs.).

 

2505.2Any one axle exceeding eighteen thousand pounds (18,000 lbs.) shall be equipped with four (4) properly inflated conventional-type tires or with two (2) properly inflated wide-base tires designed specifically for application as a replacement for conventional dual tires and rated equivalent in load carrying capacity.

 

2505.3For the purposes of this section, an axle load shall be defined as the total load imposed upon the highway through all wheels whose centers are included within two parallel transverse vertical planes not more than forty inches (40 in.) apart.

 

2505.4A loading error or tolerance of one thousand pounds (1,000 lbs.) is allowable for axle loads, and the same tolerance shall be applied for axle or gross loads permitted by special or annual permits; Provided, that any citation for overweight violation, when the load is in excess of one thousand pounds (1,000 lbs.) tolerance, shall be the total amount between the legal or permitted load and total load. The one thousand pounds (1,000 lbs) tolerance shall not be included in the amount of weight in the violation.

 

2505.5No group of two (2) or more consecutive axles shall carry a weight exceeding the value(s) given in the following table. However, if the gross weight of a vehicle or vehicle combination exceeds seventy-three thousand pounds (73,000 lbs.), the maximum weight imposed upon the highway exerted through the wheels of any one axle shall not exceed twenty thousand pounds (20,000 lbs.) nor shall a tandem axle exceed thirty-four thousand pounds (34,000 lbs.).
