The invention belongs to the field of semi-steel radial car tire design, and relates to a run-flat tire which comprises an annular tire crown part extending in the circumferential direction of the tire, tire shoulder parts located on the two sides of the tire crown part, tire side parts located on the lower sides of the tire shoulder parts and a pair of tire bead parts arranged on the inner sides of the tire side parts in the radial direction of the tire. One to two fiber cord fabric layers are laid between a pair of bead parts, the two ends of each fiber cord fabric layer are wound around a steel wire ring from the inner side of the tire to the outer side, triangular rubber strips are arranged on the upper circumferential sides of the steel wire rings of the pair of bead parts, and an air leakage prevention layer is arranged in the area between the pair of bead parts. A plurality of steel wire cord fabric layers are arranged between the lower surface of the tire crown part and the fiber cord fabric layer; and reinforcing layers are arranged between the fiber cord fabric layers and the air leakage prevention layers of the tire shoulder parts and the tire side parts. When used under the low-pressure condition, the reinforced layer can effectively play a role in buffering flexural deformation.
Description
technical field [0001] The invention relates to the design field of semi-steel radial car tires, in particular to a run-flat tire. Background technique [0002] The types of tires currently on the market mainly include ordinary tires and run-flat tires. Although common types of car tires have certain comfort, there are certain risks in safety. [0003] Once the ordinary tire leaks, the vehicle cannot continue to move forward, and the driver cannot control the steering wheel, which is prone to safety accidents; although the run-flat tire greatly improves the safety of the vehicle, the comfort of the tire is poor during use. Can not fully satisfy the use of most of the cars currently on the market. Contents of the invention [0004] In order to solve the problem of poor comfort during the use of run-flat tires in the prior art, the present invention provides a tire under low air pressure, which can not only meet the safety performance and allow the vehicle to continue driv...
