TyreSafe has aired its concern at the implication for
road safety of skyrocketing MoT failure rates caused by defects with vehicles’
Tyre Pressure Monitoring Systems (TPMS).
More than 23,000 vehicles required a retest following
identification of TPMS issues in 2016 compared with a little over 7,000 in
2015, according to Driver and Vehicle Standards Agency data - a 212% increase.
TPMS became mandatory on all new passenger vehicles sold
after 1 November, 2014 as a safety feature to help reduce the number of
vehicles being driven with tyre pressures significantly - even dangerously -
below the recommended settings.
Such vehicles are not only more difficult to control,
increasing the risk of an incident, but also consume more fuel and wear their
tyres out more quickly.
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.
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.
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.
TyreSafe had expected the widespread introduction of this
technology to lead to an increase in MoT failures in 2016 as more cars were
equipped with these systems. However, the startling rise in failures due to
TPMS defects - more than treble - was unexpected, said the campaigning
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 when out on the road. But, clearly,
even though Britain’s motorists are being warned there’s a safety issue they’re
choosing to ignore it. Regrettably, this leap in MoT failures due to TPMS
defects underlines that a poor attitude to tyre safety is not an issue
exclusively associated with older vehicles.
“TyreSafe urges motorists to put tyre safety higher up
their list of driving priorities and check their tyres and TPMS are in
