Tyres could ‘over-inflate’ or explode this weekend with temperatures set to rise across the UK in a mini-heatwave, according to one industry expert. Drivers have been issued a warning
Motorists have been issued a stark warning as the UK braces for a mini-heatwave this weekend – with fears that tyres could “over-inflate” or even explode due to the soaring temperatures.
Graham Conway, managing director at Select Car Leasing, has sounded the alarm over the potential for tyre bursts amidst the extreme heat, posing a significant danger for drivers. With the mercury expected to hit highs of 30C in southern England come Friday and Saturday, cars are set to be put through their paces.
Tyres, being critical to vehicle safety and performance, are particularly vulnerable to weather fluctuations. Drivers may not only face increased “wear and tear” on their tyres but also serious safety risks such as blowouts, reports the Express. Graham elaborated on the issue, saying: “When your vehicle’s tyres are exposed to hot temperatures, they are susceptible to wear and tear, over-inflation and even popping. There are several factors involved in this.
“Firstly, your tyres are made of rubber, which while designed to have a high resistance to heat build-up, has a breaking point. Think of your tyres as being like rubber balloons. They can only withstand a certain amount of air being put into them before they overinflate and burst.”
He added a further cautionary note about the physics at play: “Your tyres contain a quantity of compressed air. Like all materials, this is made up of atoms and molecules that react to heat. When molecules heat up they begin to vibrate, which causes them to expand. The hotter things get, the more the compressed air pushes against its container – your tyres.
“Another reason why heat can damage your tyres is friction. When your vehicle is moving, the rubbing of your tyres against the road generates a good deal of friction. Friction creates heat, and so naturally makes your tyres hot. During a heatwave, friction will cause your tyres to become even hotter than usual.”
Halfords, the motoring parts store, has issued a warning about a “significant risk” of tyres failing on drivers. They stated: “When your tyre pressure is too high, it can significantly increase the risk of a blowout. Also, less of the tread is in contact with the road, reducing traction. You’re less safe as a result, and you’ll notice less responsive handling while driving.”
The RAC, breakdown experts and car insurance specialists, have also emphasised the risks associated with hotter climates. They suggested that road users can mitigate potential risks by making minor adjustments to where they park their vehicles.
The RAC advised: “Inspect your tyre for wear and make sure they’re properly inflated, this can lead to blowouts. Try to park in shaded areas to avoid direct sunlight as this can exacerbate damage.”
