British drivers could be hit with a £2,500 fine for failing to follow a crucial tyre pressure rule, according to experts. Steve Brown, Divisional Manager at Just Tyres, warned that tyres can appear perfectly legal while still putting road users at risk of hefty fines and penalty points on their driving licence.
Under the Construction and Use Regulations, car owners must ensure their tyres are inflated sufficiently for the road. Even a small loss of pressure can have serious consequences, with drivers likely to feel the financial impact.
Tread depth is not the only factor
Speaking exclusively to The Express, Steve said: “Most drivers know that tyres need at least 1.6mm of tread. But tread depth isn't the only thing that matters.”
“A tyre that is 6 to 8 PSI below its recommended pressure can look completely normal. Particularly on modern cars with wide, low-profile tyres. It’s such a small loss of pressure that there often aren’t any obvious signs that something is wrong.”
Previous research from National Highways suggests that just one in six drivers check their tyres before setting off on a long journey.
Fuel costs and other risks
It’s not just financial penalties, with underinflated tyres likely to increase rolling resistance and burn through fuel. At a time when petrol and diesel costs continue to soar, keeping journeys fuel efficient can be just as important. A tyre just 20% under-inflated can increase fuel consumption by as much as 2%.
National Tyres and Autocare said that over-inflated tyres are also a concern as this could impact road grip and contribute to uneven wear. KwikFit said that manufacturers will specify the suitable pressure for tyres, claiming it was the driver’s responsibility to make sure that the pressure is checked and is safe.
How to check tyre pressure
Just Tyres have urged road users to check their tyre pressure readings, with details usually found on a sticker inside the driver's door frame. Information on pressures is also located inside the fuel flap or in the vehicle handbook.
Steve added: “Check all four tyres when they are cold, and use the pressure recommended by your vehicle manufacturer.” Motorists still concerned can go and secure a professional opinion from a mechanic, with many garages offering free tyre safety checks.
