Checking your tyre tread depth is a simple but vital safety check every driver should do regularly. Learn how to check your tread depth at home using a 20p coin test or a tread depth gauge.
The 20p coin test is the simplest way to check whether your tyre tread depth is approaching the legal limit. Take a 20p coin and insert it into the main tread grooves of your tyre. If the outer rim of the coin — the narrow band around the edge — is hidden by the tread, your depth is above 3mm and you are generally in good shape.
If the outer rim of the coin is visible, your tread depth is likely below 3mm. At this point your tyres are approaching the legal minimum of 1.6mm and you should consider replacing them soon. Carry out this test on multiple points across the tyre width and around the circumference to get an accurate picture.
For a more precise measurement, invest in an inexpensive tread depth gauge, available from any motor factor or online retailer. These simple tools measure the exact depth of the tread grooves in millimetres. Insert the probe into the groove and press the body of the gauge down until it is flush with the tyre surface — the gauge will display the depth reading.
Check your tread depth in at least four places across the width of each tyre and in multiple locations around the circumference. Note down any significant variation in depth across the tyre, as uneven wear can indicate alignment, pressure or suspension issues.
Most motoring experts recommend checking your tyre tread depth once a month and before long journeys. It takes less than five minutes and could save your life. Also check your tyre pressure at the same time using the gauge at any petrol station or with a home tyre inflator.
If you find that any tyre is approaching or below the legal 1.6mm limit, contact Tech Mobile Tyres to arrange a replacement. We can fit new tyres at your home or workplace across all our UK locations.
