Tyres are the leading cause of MOT failures on British roads, according to new research.
Insurance experts at Howden Insurance found tyre problems account for nearly one in five test failures nationwide through analysis of MOT test data for cars from the Home Office.
Tyres caused 7,147,058 failed tests, which represented 18.60% of all failures reported by testing stations.
Most cars failed because their treads had worn below the legal 1.6mm minimum depth.
Before your test, you can simply insert a 20p coin into the grooves of your tyre - if the outer band of the coin is visible, the tread is likely too low, and your tyres will therefore need replacing.
A spokesperson from Howden Insurance said: "Regular tyre checks should be a priority for all drivers, not just before an MOT test but throughout the year. The legal minimum tread depth is 1.6mm, but performance begins to decrease significantly below 3mm, especially in wet conditions.
"Most of these failures are preventable with routine vehicle maintenance. Drivers should be especially vigilant about checking tyres, brakes and suspension components, as these make up the majority of MOT failures.
"Taking a few minutes each month to inspect your vehicle or having regular professional checks could save both money and the inconvenience of MOT retests.”
