Is a Tire Temperature of 40 Degrees Normal?
2 Answers
Tire temperature of 40 degrees is normal. Tire maintenance tips: 1. Normal temperature: The normal operating temperature of dry tires ranges between 90 to 110 degrees Celsius. When the temperature exceeds 100 degrees, it's necessary to check the tires. 2. Normal tire pressure: Tire temperature varies depending on driving conditions and weather. If the tire pressure can be maintained between 2.4-2.6, it is considered normal. 3. Summer driving tips: Due to temperature effects, the gas inside the tires will automatically expand, causing tire pressure to rise from 2.3 kg to over 3 kg. To ensure proper tire pressure, it is recommended to fill tires with nitrogen in summer, and the filling pressure should be reduced by 10%.
Tire temperature at 40°C? That sounds quite normal. As someone who's been driving for many years, during summer long-distance trips, tire temperatures often reach this level. 40°C isn't considered high - under normal driving conditions, tire operating temperatures can rise from ambient temperature and may even reach 60-70°C without being unusual. If you just stopped the car and feel warmth when touching the wheel hub, it indicates good heat dissipation. The key is whether this temperature occurs during stationary or driving conditions. If the temperature remains this high after parking, you might need to check if the tire pressure is too high or if there's excessive load. When I measured with an infrared thermometer during highway driving, temperatures around 40°C were typical. Safety-wise, no need for excessive worry, but during regular maintenance, have the mechanic inspect tire wear, especially checking the sidewalls for abnormal aging to prevent blowout risks.
