It is Recommended that you change your tyres when the tread depth is 3mm Checks are free At D&G Autocare . Worn tyres significantly increase your chances of having an accident on wet roads by increasing the stopping distance. Significant increases in stopping distance begin to appear when the tyre is worn down below 3 mm. Although the legal minimum depth is 1 .6mm tread depth is only 1 .6mm, research has shown that tyres with 1 .6mm of tread took 36% longer to stop than those at 3mm – which represents 37 metres in wet conditions.
Failure to comply with the legal minimum standards can result in fines of up to £2500 and 3 penalty points for each illegal tyre.
