The lowest legal depth of a tyres tread is 1.6 millimetres. When thinking about a worn tyre with the legal tread limit the circumference is 0.034 metres less than a brand new tyre. Over the distance of which a car with new tyres travels at 30 miles per hour this difference in circumference equates to the car travelling approximately 0.511 miles per hour slower.
