TPMS Problems Leading to Increase in MOT Failures

Tyre Pressure Monitoring Systems or TPMS for short, became mandatory on all new passenger vehicles sold after 1 November 2014. It is a safety feature to help reduce the number of vehicles being driven with tyre pressures below the recommended settings.
But what is an excellent safety feature is now causing problems with an increase in MOT failures. According to the Driver and Vehicle Standards Agency, more than 23,000 vehicles required a retest following identification of TPMS issues in 2016 compared with a little over 7000 in 2015.
As of 1 January 2015, all vehicles first used after 1 January 2012 and equipped with a TPMS by the manufacturer must have a functioning system to pass its MOT. TPMS notifies the driver to a variance in tyre pressure by illuminating a warning light on the dashboard and, in some cases, sounding an audible alert thereby offering motorists the opportunity to rectify the issue.
This increase is something that TyreSafe, the UK charity dedicated to raising awareness of the importance of correct tyre maintenance is very concerned about. Stuart Jackson, TyreSafe chairman, said: “TPMS adds significantly to general tyre safety making it easy for the driver to know if their pressures aren’t at the right level. But, clearly, even though Britain’s motorists are being warned there’s a safety issue they’re choosing to ignore it.”
Vehicles that are on the road with low tyre pressures not only are more difficult to control, but also consume more fuel. And the tyres themselves wear out more quickly. But this massive increase in MOT failures because of TPMS defects shows that when this particular warning light comes on, drivers don’t see it as something they need to act upon.
If drivers do not see the TPMS alert come on with all other warning lights when they start their vehicle, they should immediately check with their service garage that the system is functioning properly.
TPMS helps to reduce the number of tyre-related incidents but, drivers still need to carry out regular visual checks on at least a monthly basis and before long journeys as the system will not inform them of tread depth or tyre condition.
“TyreSafe urges motorists to put tyre safety higher up their list of driving priorities,” says Jackson, “and check their tyres and TPMS are in roadworthy condition.”
