How high is the temperature of car tires when driving on highways?

There is no clear statistics on the maximum temperature car tires can reach when driving on highways, but measured data can reach 130 degrees. The following are maintenance measures for tires: 1. Ensure correct tire pressure: The standard tire pressure for different vehicles' front and rear wheels and spare tires varies. The standard tire pressure data provided by the car manufacturer is usually posted on the vehicle door pillars and other locations. If the pressure is increased by 25%, the tire life will be shortened by about 30%. 2. Tire appearance inspection: Regularly check whether the tires have bulges, cracks, cuts, punctures, or abnormal wear. Pay special attention to the wear of the tire tread and edges, as abnormal wear is often caused by poor alignment or incorrect tire pressure. 3. Keep the tire surface clean: Keeping tires clean is one of the important factors in extending tire life. Especially in winter, pay attention to tire cleanliness before and after driving. Before driving, check whether the tire tread is covered by ice or snow.
When driving on highways, I always pay attention to tire temperature, which generally rises to 70-100°C depending on speed and road conditions. With heavier loads or during hot summer days when the road surface is scorching, the temperature gets even higher. Once, I measured the tread temperature with an infrared thermometer and it reached over 90°C, which was quite surprising. During long-distance trips, the friction from the wheels generates heat quickly, causing tire pressure to rise. If not checked, this can lead to wear or even blowouts, compromising safety. Now, I stop every two hours to let the tires cool down naturally and check if the tire pressure is within the recommended range. By the way, maintaining an appropriate speed and avoiding overloading can effectively control temperature rise.
