Motorists in England are being warned to check their tyre pressure ahead of a heatwave expected this weekend, with temperatures potentially reaching 30°C. The Met Office predicts dry and sunny conditions, raising concerns about vehicle safety. Elevated temperatures can cause tyres to expand, increasing the risk of blowouts if pressure is not monitored. Drivers should refer to the label inside the driver's door frame for the correct tyre pressure, as well as ensure that they check the pressure when the tyres are cold, which means the vehicle has been stationary for at least three hours. For every 10°C increase in temperature, tyre pressure can rise by about 0.1 bar (1.45 PSI). Overinflated tyres can compromise driving performance and comfort, making regular checks crucial during warmer weather. Experts recommend that drivers also pay attention to their spare tyre, as it can lose pressure over time. If tyres feel hot to the touch, drivers should allow them to cool down before checking pressure or releasing air, as overheating can lead to dangerous conditions on the road.
