摘要

The rings (1) have a tread bar (1') and curved bars (1''), where the rings are arranged between the dual tires on the drive axles of a lorry and arranged on separate rims (2). Pressure capsules (3) are arranged among the rims and the rings and filled with vaporized aqueous liquid from a microwave radiator (4). A profile of the drive rings is resiliently engaged with a snow and ice cover, where the rings extend over a tire tread. The tread bar and the curved bars are made of heat-resistant and flexible plastic.
