Maintenance Tips Tire accessories: tire pressure monitor and anti-skid chains, extending tire service life

High quality tire accessories not only ensure driving safety, but also reduce abnormal tire wear and extend its service life (normal tire life is 3-5 years, reasonable use of accessories can extend it by 1-2 years). The tire pressure monitor is divided into internal and external types: the internal type requires tire removal and installation inside the valve, with a range of 2-3 years and higher data accuracy (error ± 0.02 bar), suitable for long-term use; The external type can be directly screwed onto the valve and installed in 5 minutes, with a price 30% -50% lower than the internal type. However, the battery life is only 6-12 months and is easily damaged by external collisions, making it suitable for temporary use or users with limited budgets. When using, it should be noted that the standard tire pressure for sedans is usually 2.2-2.5 bar, and for SUVs it is 2.4-2.8 bar. In summer, it should be reduced by 0.1-0.2 bar (to avoid high temperature tire pressure increase), and in winter, it should be increased by 0.1-0.2 bar (to enhance grip). It is recommended to check the tire pressure through a monitor once a week and before long-distance travel. The material of anti-skid chains should be selected according to the road conditions: iron chains have strong wear resistance and are suitable for muddy or icy roads with snow thickness of more than 5cm, but they are heavy, easy to scratch the wheels, and the driving speed should be controlled within 30km/h; Rubber chains (including TPU material) have good flexibility, low noise, and are suitable for roads with thin snow or mixed ice and snow. The driving speed can reach 50km/h, but they are prone to hardening at low temperatures and should be avoided from long-term use in environments below -20 ℃. In addition, after installing the anti-skid chain, it is necessary to check the tightness of the chain (preferably to be able to insert one finger), and tighten it again after driving 10 kilometers; After use, it is necessary to promptly clean the snow and sediment on the chain, dry it and store it to avoid rusting. This article will explain the selection methods, correct usage, and daily maintenance points of these essential accessories, helping you reduce tire wear, bulges, and other problems.
