Motorists urged to check tyres as summer heat risks dangerous blowouts

Rising temperatures are putting motorists at risk of dangerous tyre blowouts, with summer heat causing overinflated tyres and reduced traction.

With the UK experiencing above-average temperatures so far this summer, motor insurance experts from Quotezone.co.uk are urging drivers to check their tyre pressure. 

One in five vehicle breakdowns on motorways and A roads result from tyre defects, with a recent campaign finding that 21% of drivers who have broken down on the motorway saying it could have been avoided if they’d conducted proper tyre checks before starting their journey.

While motorists are well aware of the importance of checking tyre conditions during winter, it’s just as crucial to check tyres throughout the summer months – particularly during a heatwave. 

For every 10 degrees Celsius rise in temperature, tyre pressure can go up by about 1–2 PSI (pounds per square inch) – meaning tyres already at the upper limit could become overinflated when hot.

Overinflated tyres lead to a number of serious safety concerns for motorists, including reduced grip and traction, less responsive handling, and a higher risk of tyre blowouts – which can be particularly dangerous at high speeds. 

Before setting off on long journeys this summer, motorists are warned to carry out a few simple checks to stay safe on the road and avoid costly breakdowns. 

Greg Wilson, car insurance expert and CEO at Quotezone.co.uk said: “Many drivers carry out safety checks on their tyres throughout winter but often overlook how extreme heat can be just as tough on them.

“With the summer in full swing and many motorists travelling longer distances across the country on holiday road trips, it’s important to carry out essential safety checks before setting off.

“A quick pressure check could save drivers not only from a costly breakdown, but from a potentially dangerous tyre defect at high speed. 

“It’s essential to know the correct pressure for the vehicle, check the spare tyre, and always be mindful not to overload the vehicle – particularly if heading off on holiday with a boot full of luggage. 

“It only takes a few minutes to check the tyre pressure, but it could make all the difference.”

Tyre safety tips for motorists this summer:

1.Check tyre pressure regularly 

Tyre pressure should be checked when the tyres are cold, ideally in the morning or after the car has been parked for several hours. 

2.Know your correct pressure

Your vehicle’s manufacturer should have a recommended tyre pressure you should stick to – this can be found in the vehicle’s handbook or door sticker. 

3.Inspect for damage

High heat can soften the tyre’s rubber and worsen cracks or worn tread. The minimum legal tread depth is 1.6mm in the UK, although tyre and safety experts recommend 3mm.***

4.Adjust the pressure if necessary

If tyres have become overinflated, let them cool before adjusting the pressure. Never deflate a hot tyre based only on a hot reading. 

5.Don’t neglect the spare tyre

Something that is often overlooked, but make sure to check the pressure of any spare tyres too, should you need to use them in an emergency and note they sometimes have a different recommended pressure to the existing tyres.

6.Avoid overloading your vehicle

Not only is it illegal, but overloading a vehicle puts a lot of stress on a car’s tyres. The extra heat and pressure can also increase the risk of a tyre blowout.

Faulty tyres could land drivers £10k fine … and 12 points

October is Tyre Safety Month, the annual reminder to make sure vehicles’ wheels are roadworthy. 

Motorists using illegal, defective or under-inflated tyres can lead to serious outcomes and in 2019 contributed to 5 fatal collisions and 136 serious collisions according to figures from the Department for Transport.

Motoring charity TyreSafe, the driving force behind the initiative, highlighted the extent of the issue in 2016, commissioning research that revealed over 27% of the 340,000 tyres analysed were illegal due to inadequate tread.

Many police forces across the country support Tyre Safety Month and will be eagle-eyed when it comes to tyre inspections on routine checks.    

Car insurance comparison experts Quotezone.co.uk are warning motorists could face another issue – both large fines and hikes to their insurance premiums if they drive with defective tyres. 

Motorists can be fined up to £2,500 for each faulty tyre and receive three points on their driving licence. If the police see another tyre falling short of the law, it doubles to £5,000 and 6 points. Four faulty tyres could even see the maximum 12 points – resulting in the loss of a driving licence.

Commercial vehicle drivers, where the car or van is owned by their employer – could land firms with penalties of up to £20,000.

The legal minimum tread depth for cars in the UK is 1.6mm. These grooves help to remove water from the contact patch between your tyres and the road surface meaning the car can brake, steer and accelerate properly.

Greg Wilson, Founder of car  insurance comparison website Quotezone.co.uk, comments: “While the complexity of insurance premium calculations makes it impossible to put a pounds-and-pence figure on it, on average three penalty points could result in a 5% jump in a driver’s car insurance premium, while six penalty points could see the cost of their insurance rise by a painful 25%.

“Also bear in mind that most driving convictions must be declared to insurance providers for five years – even if the penalty points are removed from your licence after four, so motorists with points on their licence could be hit year after year until they’re spent.

“With many cars being parked at home over the past year due to various lockdowns and people working from home, it’s possible tyres might be in better condition than normal, with fewer miles potentially resulting in less wear and tear. However, it is still crucial that drivers do proper checks before travelling – long periods without driving can cause its own problems such as issues with the battery.”

Quotezone.co.uk has created a Winter Driving Checklist, to help motorists prepare for travelling in the darker and colder weather:

  • Check that windscreen washers are working and topped up with water – the bottle may need emptied out if the car hasn’t been used, to unclog blockages from debris
  • Check the battery by going for a short trip close to home first
  • Check tyre pressure and that each tyre has more than 1.6mm of tread i.e. can hold a 20p in place
  • Check tyres for lumps, bumps or cuts and remove any stones and debris
  • Check oil levels
  • Check you have a breakdown kit – jump leads, safety triangle, torch with extra batteries, empty fuel can
  • Check you have a winter emergency kit – blanket, bottle of water, phone charger, first aid kit, de-icer
  • Check if your car insurance policy includes breakdown assistance and home start, and consider signing up for standalone breakdown cover if it isn’t included
  • If the car is electric, make sure you have a full charge before setting off – winter roads can lead to unexpected deters and delays. Ideally, keep a portable battery booster in the boot in case you need an emergency recharge somewhere unexpected.
