What is the appropriate tire pressure in summer and winter?

[Branden]

In summer, it's around 2.3, and in winter, it's approximately 2.4. Summer temperatures are relatively high, so it's recommended to reduce tire pressure by 0.1~0.2. In winter, when temperatures are lower, it's advisable to increase tire pressure by 0.1~0.2. For ordinary sedans, the front tire pressure ranges between 2.0--2.3, while the rear ranges between 2.2--2.5. Tire pressure standards are related to tire type and vehicle model: Different vehicle models have varying weights, heights, and tire sizes, thus requiring different tire pressures. Standard tires have a pressure of 240kpa-250kpa, while reinforced tires have a pressure of 280kpa-290kpa. Factors affecting tire pressure: Tire pressure is also significantly influenced by seasonal factors. In summer, high temperatures cause tires to heat up during driving, and high pressure can easily lead to tire blowouts, so the pressure should be slightly lower. In winter, tire pressure should be a bit higher than in summer due to thermal contraction and expansion, so generally, a tire pressure between 250kpa-280kpa is more suitable for cars in winter.
