MOT failure rates caused by defective Tyre Pressure Monitoring Systems (TPMS) have more than trebled, which has serious implications for road safety, according to TyreSafe.

Faulty TPMS leading to 'skyrocketing' MOT fails

The tyre safety group has voiced its concerns after revealing that more than 23,000 vehicles required a retest following identification of TPMS issues in 2016, compared with a little over 7000 in 2015 – an enormous jump of 212%.

Stuart Jackson, chairman of TyreSafe, warned: “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.”

TPMS notifies the driver of any changes 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 check their tyres.

It 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 below the recommended settings.

Since 1 January 2015, all vehicles first used after 1 January 2012 and equipped with a TPMS by the manufacturer have required a functioning system to pass an 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 dramatic rise has raised serious road safety concerns, prompting TyreSafe’s warning.

Jackson stressed: “TyreSafe urges motorists to put tyre safety higher up their list of driving priorities and check their tyres and TPMS are in roadworthy condition.”

A flashing TPMS light on the dash indicates a TPMS system problem and is likely to mean a broken sensor, while a solid (not flashing) TPMS light indicates that one of the tyres has low pressure and may need to be repaired or replaced.

etyres offer a comprehensive TPMS service and its nationwide network of mobile tyre fitting experts are trained and equipped to service, replace and programme the technology without the need to go to a garage or main dealer. etyres prices are also generally much lower than the main dealers and customers benefit from having the job completed at their home or work.
