Is Higher Tire Pressure Better in Winter?
1 Answers
Cold winter temperatures can cause tire pressure to drop, so it's advisable to increase the standard tire pressure by approximately 0.2bar as a guideline. Normal tire pressure reference standards: According to the international GBT2978-2008 standard, standard tires should have a pressure of around 2.4-2.5bar, while reinforced tires should be around 2.8-2.9bar. In summer, it's recommended to follow the lower limit of the standard tire pressure, generally about 0.1bar lower than the standard, to prevent blowouts due to high temperatures. Effects of too high or too low tire pressure: Excessive tire pressure increases tire friction and reduces adhesion, affecting braking performance. It can also cause steering wheel vibration and deviation, reducing driving comfort. Insufficient tire pressure leads to a significant increase in friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a rapid decrease in strength. High-speed driving under such conditions may result in a tire blowout.
