Does temperature affect tyre pressure?


Yes, despite the relationship between temperature and tyre pressure being quite complex. temperature can have an impact on a tyre’s air pressure.

As temperature rises, the air inside the tyre expands – increasing the level of pressure. On the other hand, as the temperature drops, the opposite happens. The air contracts, and pressure decreases.

Therefore, it is essential to check tyre pressure regularly.

Can hot weather affect tyre pressure?

Yes, hot weather can affect tyre pressure.

In hot weather conditions, the air inside the tyre expands, causing the pressure to increase. For every 10°C increase in temperature, the tyre pressure can increase by approximately 0.1 to 0.2 bar.

Therefore, it is important to check the tyre pressure regularly and adjust as required.

Can cold weather affect tyre pressure?

Yes, cold weather can affect the air pressure of a tyre.

In cold weather conditions, the air inside the tyre contracts, causing the pressure to decrease.

For every 10°C decrease in temperature, the tyre pressure can decrease by approximately 0.1 to 0.2 bar.

Therefore, it is important to check the tyre pressure regularly during particularly freezing cold weather spells and adjust it as needed.

It is also worth noting that if the temperature drops significantly, the tyre pressure may drop below the recommended level, which can lead to poor fuel economy and even tyre failure.
