According to a study by mytyres.co.uk, more than half of motorists allow their tread to fall below regulation levels before changing them.
When questioned as to what would encourage them to take action, 54 per cent said low tread depths, while 62 per cent stated it would take bulges and cracks before they did anything.
A spokesman for Delticom AG, which operates in the UK as mytyres.co.uk, said that the results are cause for alarm.
"Tyres are without a doubt one of the most important safety components on a vehicle, so it is worrying that such a large number of car drivers could be on the roads with illegal tyres," the representative added.
According to a piece in the Abbotsford Times, wheel cleaners should be used to help get a car looking good for the spring.
