Temperature Rise of Vehicle Tire at Braking

ABSTRACT When a vehicle brakes, the heat generated by friction will increase the temperature of the tire tread and cause thermal wear, which will reduce the tread’s thickness or destroy the tread pattern’s integrity, thereby affecting the tire friction performance. While existing research primarily focuses on optimizing braking distance under ideal tire slip ratio (SR) through antilock braking systems (ABSs), little attention is given to whether this could lead to potential adverse consequences of increased tire temperature and thermal wear. Moreover, there is a lack of studies examining tire temperature and thermal wear under nonideal SRs. To address this gap, a MATLAB model is developed to simulate tire dynamics and estimate tread temperature across diverse braking scenarios. Results indicate a strong linear relationship between braking distance and tire temperature under ideal SR across different road conditions. ABS is an effective mechanism for reducing tire thermal wear and preserving tire friction performance. Interestingly, at higher SRs, a particular scenario arises wherein braking distance is elongated while tire temperature remains low. Additionally, the study discusses the influence of air convection cooling on tire temperature fluctuations. This study provides insights into the effects of ABS and SR on tire thermal wear.
