Tread Depths

Current tread depth legislation requires that car tyres must have a minimum of 1.6mm of tread in a continuous band throughout the central ¾ of the tread width and over the whole circumference of the tyre.

To help drivers recognise when their tyres are nearing the legal limit, tyres are manufactured with tread wear indicators in the grooves. These are bars across the grooves – when the tread depth has dropped to these indicators, the tyre will need replacing
