Drivers are at more risk of a serious accident by failing to regularly check their tyre pressures.
The stark warning by TyreSafe, the UK's leading tyre safety organisation, comes as part of its Tyre Safety Month.
While many motorists understand that insufficient tread depth can hamper a vehicle's stopping distance, many are unaware of the effect that tyre pressure can have on vehicle performance.
When a tyre is under-inflated, the tyre contains insufficient air to support the weight of the vehicle, which adversely affects acceleration, braking and cornering.
Rob Beddis, chairman of TyreSafe, said: "Without regularly ensuring that tyres are correctly inflated, motorists risk compromising the way that their car behaves on the road."
New research conducted by TyreSafe highlights that reduced vehicle performance may be affecting half of motorists on the UK's roads, as a result of not checking their tyre pressures.
"Checking tyre pressures is a simple maintenance activity that is free and takes only a few minutes each month to complete," Mr Beddis added. "By following these guidelines, motorists can ensure that their vehicle continues to behave in the way it should and they can continue to drive safely on the roads."
