337. Wheels under pressure: This section applies to vehicles mounted on wheels under pressure whose weight, to which the rated load is added, is 4,500 kg or more. A wheel is composed of a one-piece or multi-piece rim assembled with a compatible tire.
Work on a wheel under pressure, including handling and inspection, must be carried out according to trade practice.
The inflating of tires must be done according to trade practice, in particular by using a holding device that prevents the projection of wheel components, such as a cage, support, chain, bar assembly or, in the absence of such device, any other means that ensures the safety of workers.
