What Does Hot Melt Tire Mean?

[StDerek]

Hot melt tires refer to tires whose surface melts or becomes gel-like at certain temperatures. Specific details are as follows. Full Hot Melt Tires: Full hot melt tires refer to tires whose tread melts into a gel-like state when the temperature rises. When a vehicle is in motion, the tires continuously rub against the ground, generating heat in the tread. Compared to the rubber in a cold state, it becomes more fluid, meaning it softens. The softened tires enhance adhesion to the ground, thereby improving the vehicle's cornering limits. Generally, full hot melt tires are more commonly used in racing cars and are relatively expensive. Semi-Hot Melt Tires: Due to the high cost of full hot melt tires, semi-hot melt tires were developed. Tire manufacturers add chemical materials such as Kevlar fibers during production, which strengthens the sidewall hardness while reducing weight. These tires operate at much lower temperatures than full hot melt tires but still retain some hot melt characteristics. Combined with tread pattern and drainage groove designs, they can achieve grip levels close to those of full hot melt tires.
