When drivers are applying tyre cleaners to their rubber, they must also check that the wheels are road legal.
That is according to Swinton, which found that general car maintenance is something that a lot of British motorists are neglecting.
Just under a quarter have no idea whether their tyre tread meets the 1.6 mm required by law, while less than a third check their tyre pressure.
A further 27 per cent ignore warning signals on the dashboard.
Steve Chelton, insurance development manager at Swinton, said that the need to carry out regular maintenance is something that should not be underestimated.
"Looking after your car has so many benefits in terms of safety, fuel efficiency and car value that it is in the car owner's best interests to do so," he added.
Recent research from Hycote found that half of motorists fail do any checks before they set off on long journeys.
