Drivers issued urgent heatwave warning over little-known change to tyres

Drivers have been told to check their tyre pressure this week as temperatures crank up to a balmy 29C in parts of Britain. High temperatures are known to cause various issues for your , and by performing this simple check, you can save yourself from costly repairs.

Hot temperatures can cause tyre pressure to dramatically increase, which can lead to a higher risk of encountering a blowout on the road. Due to the principle of thermal expansion, tyres will expand in hot weather.

As the temperature continues to rise, the air inside the tyres will expand, ultimately occupying more space and increasing the internal pressure. At the same time, friction from the road surface and the constant flexing during turns can also build up heat and overinflate the tyre, which could lead to a blowout.

A tire blowout is characterised by the rapid loss of air pressure, which can lead to a loss of control, making the vehicle difficult and potentially hazardous to you and others on the road. Additionally, a blowout can also damage the wheel and the surrounding areas of the car.

Sam Sheehan, motoring editor at , has since urged drivers to double-check that all tyres are inflated to the manufacturer’s recommended pressure, which can be found in the car manual or on a sticker inside the driver’s door frame.

Sheehan says: “Your tyres warm up when you drive, and you can get a false pressure reading when they’re warm. Check your tyres before you set off, when they’re cold, for an accurate reading. It’s best to check your tyre pressure (and for any signs of wear and tear) regularly.”

Not only is tyre pressure a risk factor for drivers this spring, but it’s also essential to closely monitor your car battery. Batteries are costly to replace, so maintaining their health is vital. Hot weather can cause the batteries to overheat, resulting in the evaporation of battery fluid and reduced battery life. Sheehan explains: “Your battery should be checked during a service, but it doesn’t hurt to give it a once-over before the summer properly kicks in.”

He adds: “If your battery is over three years old, consider having it tested by a professional to make sure it’s all good.”

As we continue to enjoy this lovely weather, be sure to keep a close eye on your tyre pressure and car battery to avoid costly repairs or serious accidents.
