Is Tire Pressure Related to Weather Temperature?
1 Answers
Temperature has a significant impact on tire pressure. After exposure to intense sunlight, tire pressure can become very high and requires driving to cool down. Prolonged high-speed driving also increases tire temperature. The higher the temperature, the lower the air pressure, compared to surrounding areas at the same altitude. This comparison is not made vertically, as in the vertical direction, temperatures and air pressure are higher near the ground and decrease with altitude. Excessive Tire Pressure: When tire pressure is too high—significantly above the standard pressure—it reduces tire friction and grip, affecting braking performance. This can cause steering wheel vibration, veering, and decreased driving comfort. Additionally, it accelerates wear on the central tread pattern, shortening tire lifespan, increasing vehicle vibration, and indirectly affecting the longevity of other components. Insufficient Tire Pressure: When tire pressure is too low—significantly below the standard pressure—it increases the friction coefficient between the tire and the road surface, leading to higher fuel consumption. It also makes the steering wheel heavy and prone to veering, posing safety risks. Insufficient tire pressure increases movement in various parts of the tire, causing excessive rolling and abnormal heat generation.
