What is the most common vehicle defect causing accidents? Braking failures? No – braking comes a close second to tyre defects at 36% (braking defects at 31%).
In 2013, more than 2.2 million MOT failures were due to tyre defects. TyreSafe found that of tyres tested after removal for replacement 57% where found already to be illegal.
Have motorists become complacent? Are they too reliant on their vehicles to inform them when something is wrong? The majority of cars will tell you when the fuel tank is close to empty, when the oil level is low and when the tyres need air. But – for the moment at least – cars do not inform you about dangerous tread depths.
Checking the tread depth is simple – yet 1 in 5 motorists have never done it. Take a 20 pence piece and place it within the tread of the tyre – coincidentally, the raised edge around the side of the 20 pence piece is 1.6 mm – if you can see the raised edge of the coin than your tyres require immediate replacement.
The sale of part worn tyres was also highlighted at the briefing as a serious problem – the majority of tyres checked for resale as part worn were not found to have been certified as fit for purpose, and many were found to have reached illegal tread depths.
Stuart Jackson from TyreSafe explained that tyre defects were associated with 981 persons killed or seriously injured in the 5 year period to 2013, over £0.4 billion, while the Highways Agency’s Stuart Lovett says 66,500 incidents related to tyre defects occurred on the motorways network in the 18 months from April 2013 to September 2014. This amounts to approximately 100 incidents a day – and that is without considering any roads outside the motorway network.
This is not just a HGV issue either – 63% of motorway tyre breakdown issues involved a car, with only 21% involving a HGV.
The focuses for improving tyre safety include enforcement and education.
Enforcement is not a simple matter – police budgets are stretched. But December will see the start of a project funded by TfL for the enforcement of tread depth regulations, amongst others, on HGVs. Education involves informing people about the real dangers of bald tyres, how often they should be checking them and the 20 pence piece method for doing so. TyreSafe Safety Month, occurring last month is a part of this education process.
