Experimental and CFD Analysis of Tire Cooling Sidewall

Tire durability can be guided by fracture mechanics, where stress and temperature state in rubber play a key role. The temperature influences the fatigue metrics, such as crack propagation speed, with a significant nonlinearity, therefore temperature reduction in the visco-elastic media is known to be effective in enhancing the product life.

This paper introduces a new method to reduce the temperature by increasing the heat transfer across tire sidewall surface.
