Effect Of Ambient Temperature And Inflation Pressure On Tire Temperature 2019-26-0360

Tire failure is identified as a major cause of accidents on highways around the world in the recent past. A tire burst leads to loss of control of the vehicle which ends up in a catastrophe. There are various factors which are accounted for a tire burst. Heat buildup, ageing of tire and cracks on tires are the major ones which are identified. A superior ability of the tire to dissipate the heat generated during operation is a major factor which prevents a tire failure. Other factors such as ambient temperature, inflation pressure etc. contributes to heat buildup which may ultimately result in tire failure. A combination of these factors might manifest as a tire failure at high speeds, the latter being an immediate cause of heat buildup. A dormant crack in the tire might develop if the temperature and pressure conditions are favorable, thus giving away at the weakest point. With regard to the temperature conditions, road conditions, inflation pressure checks etc. India is vulnerable to tire failures. It may be noted that present regulations in India does not mandate temperature resistance testing. The paper tries to examine the effect of ambient temperature and inflation pressure on tire surface temperature build up. Ambient temperature and inflation pressure conditions shall be altered to study the heat buildup in the tire samples. The testing cycles shall also be varied to plot the behavior of tire temperature in various cases.
