According to tyre maker Michelin, motorists who want to keep their cash in their pocket and not waste money need look no further than the wheels of their car.
They explain that because an averagely under-inflated tyre uses roughly three per cent more fuel to force its way along the road, a driver could be wasting up to €100 a year or more all for the sake of keeping their tyres pumped up.
Ideally, Michelin recommends that drivers check their tyre pressure every month, and before each long journey.
A survey last year found that many drivers didn't know the correct tyre pressure for their car while a huge percentage relied on a partner or mechanic to check the pressure.
