In winter, truckers and heavy truck drivers use plastic containers to prevent the wheel from jamming. This method is mainly used for trailers, since a powerful tractor can move without effort.
On trailers, the driver does not notice that the jammed wheel begins to wear out and burst when the truck moves. They cannot see this process because the trailer is long. To solve the problem, truckers install plastic containers and can easily see the moment of slipping or scrolling in the rear-view mirror. The container is mounted in such a way that its bottom protrudes slightly beyond the border of the tire. They also try to use colored plastic so that it can be seen from a distance.
Another reason for use is to protect against freezing of bolts or nuts. In severe frosty weather conditions, the wheel bolts on the wheel freeze. If the tire starts to crackle or burst, the trucker simply cannot perform its replacement. To protect from this, bottle caps are used, and the bolts are closed with them. We also note that bottles are mainly installed on tubeless tires, since when they become jammed, they wear out faster than tube tires.
