What is the weight per axle on a 10 wheeler?

Answer 1

Vocational trucks are allowed more weight per axle than a tractor and semi trailer. The overall allowed gross weight depends on a number of factors... type of road they're on, wheelbase, etc. Typically, a gross weight of between 52,000 and 54,000 lbs. is allowed. Typically, the drive axles are allowed a combined weight of 34,000 lbs... some states have higher weight allowances grandfathered in from before the federal bridge law went into effect (e.g., you're allowed 36,000 on a set of tandems in Colorado). The steer axle can be up to 20,000 lbs, so long as the axle and tires are rated for it... you wouldn't be allowed to gross 20,000 on that axle if you're running a 14k axle and tires.
