When sliding, at least five axes are required. Self-propelled or towed vehicles may have fewer than five axles. *As indicated by the manufacturer on the side panel. Metric to inch conversion: Divide the metric size by 25.4 (i.e. 285 ÷ 25.4 = 11.22 inches). ** Fixed, driver-operated steered axles with single tires are limited to 600 pounds per inch wide. Unlike the steered axle, axles that carry more than 10,000 pounds and are equipped with single tires are limited to 500 pounds per inch wide.

The axle load on an axle would be a weight of more than 20,000 pounds on a single axle and 34,000 pounds on a set of tandems. The weight of the tridem would depend on the measurement between the three axes. After determining the distance, check the vehicle`s weight chart to see what the legal capacity would be. The price of the licence is calculated according to the weight greater than the legal weight per axle and the number of kilometres to be driven. Weight: Single axis: 20,000 lbs Tandem axle: 34,000 lbs Tridem: 42,000 lbs Gross weight: 80,000 lbs The lowest of these calculations determines the capacity of each series of axles. The permissible weight of any row of axles may be calculated according to the following formula: The Department may issue special permits to vehicles operating in the Tacoma Port Heavy Vehicle Industrial Corridor to carry a weight greater than the weight limits specified in RCW 46.44.041.
