2023 guide on how to care for your tyres during a heatwave

Monday 18th July 2022

The current heatwave might feel like a welcome change from the usually underwhelming British summer climate, but it can have an effect on your tyres, and it’s important to understand how.

How can the heat impact my tyres?

As the temperatures rise, so does the heat of the air inside your tyres, causing the pressure to increase. This increase in pressure can lead to overinflation of the tyres, which can result in damage such as cracks, tears, or even a blowout.

Generally, for every 10 degrees the temperature increases by, and tyre pressure can go up by around 0.1 bar, even if the car hasn’t been driven. Although this seems like a minor amount, any change in pressure can cause problems.

If your tyres feel hot to the touch, this is a clear sign they could be overheating. If you’re travelling a long distance and realise your tyres feel hot, the best form of action is to wait a while for the tyres to cool down before resuming your journey.

When to check my tyre pressure

It’s best to check your tyre pressure each week during a heatwave. Do so when the tyres are cold – several hours after the car was last driven. Otherwise, if you adjust the pressure when the tyres are too warm, the gauge will register that there is more pressure in the tyres than there actually is. Meaning, if you reduce the pressure, the tyres could be underinflated once they have cooled down.

How do I find out my vehicle’s tyre pressure?

You can find your vehicle’s recommended tyre pressures in your handbook.

Find a detailed guide on how to check your tyre pressures on the AA website through a step-by-step breakdown.

Ensure you have the correct tyres

To ensure the best performance from your tyres in the warmer months it is important that you have the correct tyres. If you have your seasonal tyres on or you purchased a car with winter tyres fitted, consider swapping them to a set of or all-season tyres as these are recommended when the average daily temperature reaches above 7°C (44.6°F).

This reduces wear and may improve the fuel efficiency of your vehicle as winter tyres may become hard and brittle in the hotter weather, increasing friction.

You can also check out our blog on why you should be switching out your winter tyers this spring, which expands on the benefits and offers options for those who may want to avoid swapping their tyres out each season.
