An Insight Into How Temperature And Tyre Pressure Are Inter-Related

During school, you probably might have studied the Gay-Lussac’s Law AKA Pressure Temperature Law. As per the law, at constant volume, the pressure of any gas is directly proportional to the Kelvin temperature, which means, pressure increases with an increase in temperature and vice-versa. In a lay man’s language when a matter is heated, it expands and the same contracts when cooled down. Your tyre is also a matter which is made of rubber (synthetic and natural both), fabric, wire, carbon black, and other chemical compounds. The tyre’s body contains compressed air, which supports the weight of the vehicle; hence adequate pressure is crucial to its performance. Whether it’s fuel consumption, tyre life, or safety, all are associated with the tyre pressure.

Is Temperature Related To Tyre Optimisation?

As the temperature fluctuates, pressure also rises and falls. When it’s warm, the pressure is higher and when it’s cooler, the pressure is lower. Any air is a mixture of gases and when the temperature increases, the gas molecules start moving at a high velocity which requires more space and thus, expansion takes place.The optimal temperature of a car tyre is kept around 32 PSI (pounds/square inch). As per formula race drivers, tyre temperature plays a fundamentalrole in driving performance, and that is why they warm up the tyres (taking laps) for obtaining optimised grip when performing. With this example, you can better understand how temperature is crucial for theoptimum performance of a tyre.

Where does the heat come from?

Dark coloured material can better absorb and disperse the heat. Tyres are usually black and quickly attract and evaporates the heat. As a result, the temperature fluctuates which affects the tyre pressure.Your tyres can take heat from many sources such as:

  • The friction working between your tyre and the road surface causes heat. The tyre that is under-inflated produces more friction and more friction means more heat.

  • Roads are mostly made of dark tar which has the tendency toheat up quickly in warm weather.

  • This heat from ever-changing weather temperature also gets transferred to your tyres, especially when parked in open parking space.

  • Your tyres absorb the heat directly from the sun and transferit to the air inside.

  • Running engine contributes to the effects of heat, particularly onthe tyres set in the front.

How pressure affects my tyres?

Pressure can influence fuel efficiency, grip, handling, traction, and braking.
