Development of Double-Sided Summer–Winter Pneumatic Tires

Abstract

The article substantiates the relevance of improving the design of automobile pneumatic tires. The basic parameters of the utility model “double-sided summer–winter pneumatic tire” (Patent for utility model No. 182679), developed by the fellow workers of the FSBEI of Higher Education Pskov State University, are described. The features and main disadvantages of the closest analog (patent for the invention RU 2028953) are presented: the inability to use it year-round, an increase in the imbalance and the risk of puncture during the operation of the second tread part due to uneven wear of the first and second tread parts. The technical goal, solved by the proposed useful model, is to ensure the possibility of year-round use of pneumatic tires. The goal is achieved by the unique features: The inner part of the tire is a mirror image of the external part; one part of the tire is equipped with spikes; if necessary, the tire can be turned out. The scientific novelty of the developed double-sided pneumatic tires consists of combining two traditional products, which gives a significant synergistic effect: savings of the cost of acquisition and use, reduction of environmental damage.
