What Causes High Wheel Rim Temperature?
3 Answers
High wheel rim temperature is caused by: 1. Poor heat resistance of the tire itself; 2. External factors leading to excessive tire temperature. During hot summer days or high-speed driving, the temperature of the tires rises rapidly, and the internal air pressure of the tires increases accordingly. When the tire temperature reaches a balance between heat absorption and dissipation, the temperature and pressure of the tire will not rise further, and proper methods should be used to cool the car's tires. Different types of tires have varying degrees of heat resistance. Under normal circumstances, the maximum temperature that passenger car tires can withstand is around 180 to 220 degrees Celsius. During normal driving, the temperature of the tires is maintained at approximately 90 to 110 degrees Celsius.
I've been driving for decades and I'm no stranger to wheel hub overheating. Common causes include brake system issues, such as seized brake calipers that don't retract, causing friction-generated heat to transfer to the wheel hub. Bearing damage is another frequent culprit - old or worn bearings create excessive friction and heat buildup. Tire problems shouldn't be overlooked either; incorrect tire pressure (either too low or too high) or unbalanced towing can cause abnormal wheel temperature rise. From a safety perspective, high wheel hub temperatures can easily lead to brake failure or tire blowouts, especially during high-speed driving. I've found that regular brake pad inspections and bearing lubrication are crucial, along with adopting smooth driving habits and avoiding sudden braking. Never take this issue lightly - get it to a professional repair shop immediately when it occurs.
When I play with modified cars, I often encounter the issue of hot wheel edges, mostly caused by the brakes. Rapid acceleration followed by hard braking can overheat the calipers, transferring heat to the wheel edges. Another reason could be unbalanced modified tires or rims, leading to uneven force distribution and rapid temperature rise during spirited driving. Sometimes, suspension system failures, such as aging shock absorbers, can affect the smooth rotation of the wheels. I recommend checking if the cooling system is functioning properly, maintaining standard tire pressure, and avoiding prolonged aggressive driving. Excessive temperatures can damage components and even affect fuel consumption. Regular maintenance can save you from high repair costs.
