Half of tyres changed at illegal tread depths
Micheldever Tyres Service’s latest quarterly tread depth analysis shows that between March 2012 and March 2013 between 50 and 60 per cent of tyres taken off in depots were already below the 1.6 millimetre legal limit. A further 40 per cent were on or just above it and only around three per cent were above 2 millimetres. Flicking back to when the research began in June 2008 it is clear to see that that the situation has deteriorated markedly over the last four or five years. Back then only around 15 per cent of tyres brought into depots were already illegal. Now it is more than triple that.
