Is a Tire Temperature of 50 Degrees Dangerous?
1 Answers
Tire temperature of 50 degrees is normal. The optimal operating temperature for dry tires ranges between 90 to 110 degrees Celsius, and dry tire insulation sleeves are always maintained within this optimal range. Additionally, tires should not overheat, as excessive temperatures can turn a wet tire into an old dry tire. Below is relevant information: 1. Consequences of excessively high tire temperature: If tire temperature becomes too high, it can be very dangerous. Prolonged contact with high-temperature road surfaces causes heat accumulation to intensify, leading to a rapid decline in the mechanical properties of the tire rubber material. On the other hand, due to thermal expansion, excessively high temperatures will increase tire pressure. When the tire strength is insufficient to withstand the pressure, a blowout becomes inevitable. Driving speed: The faster a tire travels, the quicker it generates heat, the higher the temperature rises, and the greater the impact force it experiences—these factors are directly proportional. Therefore, under high speeds and high temperatures, tread wear accelerates, and it is advisable to choose a reasonable speed for driving. 2. Countermeasures: In summer, road surface temperatures often exceed 70°C. Cars driving for extended periods in hot summer conditions with damaged or weak tires are highly susceptible to blowouts due to excessive tire pressure. Experts point out that due to temperature effects, the gas inside tires automatically expands, causing tire pressure to rise from 2.3 kg to over 3 kg. To maintain proper tire pressure, it is recommended to fill tires with nitrogen in summer and reduce the filling pressure by 10%.
