Abstract

The invention discloses a light truck tire. The light truck tire comprises a tire body, wherein the tire body is provided with a tire tread; the tire tread comprises tire crowns, tire sides and tire shoulders; the tire sides are arranged perpendicularly to two sides of the tire crowns; the tire shoulders are connected with the tire sides and the tire shoulders in a smooth transition mode; the tire crowns are provided with two circles of continuous-tire-crown type pattern block sequences extending along the circumference directions of the tire crowns; the continuous-tire-crown type pattern block sequences comprise a plurality of zigzag tire crown pattern blocks which are sequentially ranked at intervals along the circumference directions of the continuous-tire-crown type pattern block sequences. The left tire crown and the right tire crown which are provided by the invention are respectively provided with left zigzag tire crown pattern blocks and right zigzag tire crown pattern blocks correspondingly, so that the tire crowns can obtain relatively high tire tread rigidity, thereby improving the abrasion resistance and transportation stability of the tire, reinforcing the design of the tire body structure, and improving the load resistance of the tire effectively.

Description

technical field [0001] The invention relates to a tire, in particular to a light load tire. Background technique [0002] At present, the matching tires for light vans and trucks sold in the domestic market are mainly radial tires for ordinary passenger cars. However, with the rapid development of my country's economic construction and the improvement of people's living standards, there are more and more cases of overloading of light vans and trucks, and the problems of poor load resistance and non-wear resistance of ordinary passenger car radial tires are gradually show up. Contents of the invention [0003] In order to solve the above problems, the present invention provides a light duty tire with good load resistance performance. [0004] The technical scheme of the present invention is as follows: a light-duty truck tire includes a tire body, the tire body has a tread, and the tread includes a crown, sidewalls and shoulders, and the crown is divided into left and righ...
