Thanks to Bude Tyres for drawing this to Bude & Beyond’s attention so let’s spread the word. Tyresafe.org has plenty of information to help keep people safe on the roads.
Here’s their info on car tyres:
Tread depth is important to maintain good grip on wet roads but, as the tread wears down, the tyres will lose the ability of good grip. The ‘20p test’ is a quick way to check the tread depth. Place a 20p coin into the main tread grooves at three points across the tyre and then repeat around its circumference. If the outer band is visible, the tyres may be unsafe or illegal and need to be checked by a tyre professional. Tyre pressure is equally important. Having the right pressure ensures the car handles as it should, reduces the risk of a sudden deflation and helps keep fuel consumption of the vehicle at its optimal level. The car manufacturer typically displays the correct pressures in the door shut or filler cap, but it can always be found in the owner’s manual or on TyreSafe’s pressure checker. Remember there are two pressures – one for normal loads and the other when fully laden. While you’re checking pressures, it’s a good opportunity to have a look at the tyre’s condition. Tyres are never manufactured with lumps, bumps or objects sticking in them, so if you see any of these, you’ll need to have the tyre inspected. If objects like stones are wedged in the tread, remove them if you can.
- Air pressure: Use an accurate tyre pressure gauge to check tyres’ air pressure is at the recommended settings (life has been much easier since I invested in one of these). Check the vehicles owner’s handbook or fuel filler ca.
- Condition: Lumps or bulges in a tyre may indicate internal damage and increase the risk of a catastrophic failure. If these, or cuts and cracks, are found while checking a tyre, the tyre may need replacing and professional advice should be sought.
- Tread depth: Tread depth should be checked with an accurate gauge to ensure it is above the minimum legal limit of 1.6mm. If you don’t have an accurate tread depth gauge, a 20p can be used as a guide to how close your tread is to the limit if you don’t have a tread depth gauge available
