Inspect your Tyres
Inspect your Tyres
The legal tyre tread depth in the UK is 1.6mm across the tyre's central three-quarters. So if you measure 3mm on one part, but it's 1.6mm elsewhere, you need to change your tyre. And don't worry if you don't have a tyre tread gauge. You can still use the tyre tread indicators on the tyres or a 20p coin by inserting it into the tyre tread grooves. Using the outer band on the 20p as a measurer, if this band disappears into the tyre grooves and isn't visible, your tyres are legal. However, if you can see any part of the coin's outer band, your tyres are below the legal limit and unsafe. Also, ensure you have a good look all the way around and check for any bulging or damage to the tyre wall which will also cause an MOT to fail.
We also recommend checking that your tyres are inflated correctly per the manufacturer's recommendations in your vehicle's handbook. Whilst tyre pressures aren't part of the MOT, if any tyres are visibly under-inflated, the MOT tester could fail the car; checking tyre pressures is worth it to avoid any unnecessary disappointment.
