October's tyre safety month is underway and 7 year-old ‘mechanics' Kyanne and Finlay are urging drivers to take the 20p test in order to stay safe and legal. The pair's appeal can be seen in an online movie (www.tyresafe.org) where they show drivers just how simple and easy it is to check their tyre tread depth.

"Checking that your car's tyres have adequate tread depth is extremely simple and easy," explains Stuart Jackson, chairman, TyreSafe. "As our two ‘mechanics' demonstrate in the campaign movie, you don't need any specialist tools or knowledge. A simple 20p coin and a few minutes is all it takes. With such potentially devastating and life-changing consequences, drivers should ask themselves if they can afford not to take the test?"

Adequate tread depth is critical to road safety, particularly in wet conditions as the tread grooves help to remove water from the road surface. Without sufficient tread depth drivers may suffer from a loss of grip or traction leading to longer stopping distances, reduced handling and an increased likelihood of aquaplaning.
Current UK law requires car tyres to have a minimum of 1.6mm of tread across the central three quarters of the tyre, around its entire circumference. Drivers found to be in breach of these regulations face a fine of up to £2,500 and three penalty points for each illegal tyre.

In addition to the online video, hundreds of garages and tyre retailers across the country will be offering free tyre safety checks. To find out more about tyre safety visit www.tyresafe.org.

How to take the 20p test

1. Tyre tread depth should be checked at least once a month at the same time that you check your tyre pressures.
2. A 20p coin provides a useful alternative to a calibrated tread depth gauge.
3. Insert the 20p coin into the main tyre grooves at several places around the circumference of the tyre and across its width.
4. If the outer band of the 20p coin is visible whenever you insert it into the grooves, your tread depth may be illegal and you should have them checked by a qualified tyre specialist.
5. When checking your tread depth, give the rest of the tyres a visual inspection for any cuts or bulges and remove any stones or objects embedded in the tread.
6. If in doubt, visit your local garage or tyre dealer.
