What is the right tire pressure in winter？

In winter, the tire pressure adjustment of automobile tires should be based on the standard air pressure, and it should be appropriately raised by about 0.2bar to ensure driving safety.

Proper tire pressure is very important for automobile driving. Excessive tire pressure will reduce the friction and adhesion of tires, affect the braking effect, and may lead to steering wheel vibration and deviation, reducing driving comfort. At the same time, too high tire pressure will also accelerate the local wear of the central pattern of the tire and shorten the service life of the tire. In addition, too high tire pressure may also make the tire cord stretch and deform excessively, reduce the elasticity of the carcass, increase the load of the car while driving, and reduce the rolling resistance, thus increasing the risk of tire puncture.

On the other hand, too low tire pressure will also bring many problems. Too low tire pressure will increase the friction coefficient between the tire and the road surface, leading to an increase in fuel consumption. At the same time, too low tire pressure will make the steering wheel heavy and prone to deviation, which is not conducive to driving safety. In addition, too low tire pressure will also increase the amount of exercise in all parts of the tire, and excessive rolling will cause abnormal heating of the tire, reduce the functions of the cord and rubber, and cause damage such as delamination or cord breakage. In severe cases, too low tire pressure may also lead to a double increase in friction between the tire and the ground, a sharp increase in tire temperature, and a sharp decline in tire strength, which may eventually lead to a puncture.

Therefore, when adjusting the tire pressure of automobile tires in winter, the principle of standard air pressure and appropriate upward adjustment should be followed to ensure driving safety.

Set up a volunteer team to carry out public welfare activities … At present, Tongbei Fitness has formed a new national fitness project mainly in Xicheng District, covering eight urban areas in Beijing, more than a dozen provinces, autonomous regions and municipalities across the country, with hundreds of teams and tens of thousands of people participating. In 2022, Tongbei Fitness was selected into the National Fitness Volunteer Service Project Library of the State Sports General Administration.

"I am deeply honored and responsible to be selected as the most beautiful social sports instructor in 2023." Zhang Bin said that the duty of social sports instructors is not only to impart sports skills, but more importantly, to spread a healthy lifestyle and advocate a positive outlook on life, so as to help people find happiness in sports and improve their quality of life.
