Problems solved by technology

[0002] At present, run-flat tires mean that they still have good driving ability even when they are completely deflated. Therefore, the current run-flat tires tend to solve the 0-pressure durability of run-flat tires, and do not fully consider other performance requirements. , and the need for comfort is also a key performance requirement for tires, and most run-flat tires on the market cannot take into account the dual performance of durability and comfort; even if the dual performance is taken into account, the uniformity of the tire cannot meet the requirements

Abstract

The invention discloses a run-flat tire with the excellent performance. The run-flat tire comprises a lining layer, a tire body, a tire sidewall and a tire bead. The tire bead comprises bead filler and a steel ring, the tire sidewall comprises tire sidewall wear-resistant rubber, and supporting rubber is arranged between the lining layer at the tire sidewall and the tire body; the elastic modulusM1 of the bead filler, the elastic modulus M2 of the supporting rubber and the elastic modulus M3 of the sidewall wear-resistant rubber are set to meet the following relations: 0.85 < = M2 / M1 < = 1.15and 0.85 < = M2 / M3 < = 1.15; the distance L1 from the upper end point to the lower end point of the bead filler, the distance L2 from the upper end point to the lower end point of the supporting rubber and the distance L3 from the upper end point to the lower end point of the sidewall wear-resistant rubber are set to meet the following relations: 2.5<= L2 / L1 <=3.5 and1.5<= L1 / L3 <=2.5. The durability of the tire is improved by limiting the supporting rubber, the bead filler and the wear-resistant rubber,.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a run-flat tire with excellent performance. Background technique [0002] At present, run-flat tires mean that they still have good driving ability even when they are completely deflated. Therefore, the current run-flat tires tend to solve the 0-pressure durability of run-flat tires, and do not fully consider other performance requirements. , and the need for comfort is also a key performance requirement for tires, and most run-flat tires on the market cannot take into account the dual performance of durability and comfort; even if the dual performance is taken into account, the uniformity of the tire cannot meet the requirements . Contents of the invention [0003] The object of the present invention is to provide a run-flat tire with excellent performance to overcome the above-mentioned technical problems. [0004] Above-mentioned technical purpose of the present invention is...
