The extreme heat of the summer season is likely rubbing you the wrong way. However, you may not believe what it can do to your car tires. People will often ignore the effects of the heat them. Nevertheless, this ignorance comes with a hefty price to pay in damages, and sometimes, injuries. If you want to keep your vehicle running smoothly all summer long, it is necessary, that you must adhere to certain safety measures that are adamant for your wheels.

Heat can Affect Tires

Heat does not only affect us, but it can also affect rubber. Any rubber component will react to heat over a long period, and result in compositional changes. Take into account the amounts of rubber components in them.

Nevertheless, under extremely hot conditions, car tires are something that is under most threat. This is because of the air pressure inside the car tires. A tire is a vessel with stored air. Air molecules, under the influence of high amounts of heat, begin to spread apart and move rapidly against each other.

When you consider this, you will begin to understand how the air pressure inside the tires can start to increase in the face of high temperatures. To further explain, once the temperature rises, the molecules within the tires begin to hit the inner tire walls more rapidly and frequently.

This continues until the pressure inside the tire begins to build. It increases to PSI levels that are dangerously high. This rapid vibration of air molecules and expansion of tires because of the air pressure can ultimately cause the tire to burst. However, other factors may also contribute to this outcome.


If you are driving your car on a hot summer’s day, then you are combing the external heat with the frictional heat of the car rubbing against the road. With two sources of heat to your tires, the pressure inside your tires probably rises to extreme levels.

The Rubber Material

Another thing that makes tires vulnerable to the summer heat, is in fact, the material itself. Rubber molecules intertwine together in spiraling chains, or polymers. In the face of air molecule vibration, polymers are more likely to contract. This means that the tires tend to push inwards when the air inside is pushing outwards. Even though they have the properties that coil within them, every tire reaches a breaking point.

Tires help support us and carry the weight of our vehicles through thick and thin and across rough terrains. However, it is as little as prolonged heat exposure, which can cause them to fold. Hence, you have to be extra careful during this summer.
