Is a tire temperature of 65 degrees Celsius high for a small car?
1 Answers
A tire temperature of 65 degrees Celsius is not high for a small car. Here is relevant information: 1. Normal tire temperature: The normal operating temperature range for tires is between 90-110 degrees Celsius. A tire temperature of 65 degrees has no adverse effects, as tires are equipped with insulating layers that generally maintain temperatures within a controllable range. Excessively high tire temperatures are dangerous. Prolonged contact with hot road surfaces causes heat buildup, rapidly degrading the mechanical properties of the tire rubber compound. Additionally, thermal expansion increases tire pressure. When the tire's strength can no longer withstand the pressure, a blowout becomes inevitable. 2. Controlling tire temperature: Managing driving speed is crucial for controlling tire temperature. At high speeds, most kinetic energy converts to heat, raising tire temperature. This accelerates rubber aging and reduces the fatigue resistance of the cord layers, leading to premature tire separation or blowouts. Therefore, speed limitation is essential for temperature control. Furthermore, during hot weather like summer, avoid prolonged driving. Take breaks every 2 hours or after certain distances to check tire temperature and pressure. If tires overheat with rising pressure, park in shaded areas to allow natural cooling and pressure reduction. Never deflate tires or pour cold water on them, as this may cause blowouts or other accidents.
