Recently, the Beijing Consumers Association announced the comparison test results of 26 tire samples from 13 brands. The results show that all samples meet the requirements of national standards, but some media have interpreted the "durability and low pressure" test errors as tire wear tests. . The test of tire service life requires continuous operation at a certain speed on selected road conditions. This test is a "durable and low air pressure" test for amatayala, ayo ayalungama ku kukaana ukutonta kwa matayala no kucetekelwa kwa taya pa muulu wa mwela uwacepa uwa mupashi wa mupashi uwacepa, twalonganika no kufushako amashiwi ya matayala mutanda aya ku ntanshi pa lwa kulanga kwenukwetemocitile[7}}.

A tire is a composite structural article composed of multiple materials and multiple components that is used under severe and complex conditions. During the running of the tire, the ground friction is severely rubbed with the ground, and at the same time, various stress and strain will be generated in each part. These stress strains are alternately changed at a relatively high frequency, resulting in fatigue of the tire, and shearing force is generated during use of each component. In addition, pa mulandu wa kuti umulilo wa mu matayala yapilibuka mu ciputulwa ca maka ya kupya mu nshita ya kushipikisha, pa kuti tayala yabomba pa muulu wa cipe ca mubili pa muulu(3)} Icipe ca matayala ni ntambi iyabipa iya kupya, te kuti cibe icayanguka ukufumyapo ubufuba, kabili cayanguka ukuleta ubufuba, no kucefya kwa cikabilila, ukucingililwa kwa mubili, no kukaana kwa mpasabo, no kukaana kwa mpasabo, ubucingo bwa mpasabo, ubucingo bwa mpaanga, te kuti cibe icakosa. durability test is an internationally recognized tire resistance test. An important means of heat and fatigue resistance. The endurance test is to use the drum as the active simulated road surface. In a certain temperature range, the combination of the tire and the rim filled with the predetermined air pressure is pressed on the drum according to the specified load, and the drum is operated at a constant speed.

The high-speed performance test is to evaluate the high-speed running performance of the tire according to the tire speed symbol. The high-speed performance test of the tire is to use the drum as the active simulated road surface. In a certain temperature range, the combination of the tire and the rim that is filled with the specified air pressure is pressed on the drum according to the specified load, and the test speed of the drum is gradually increased.
