Tyre wear & safety
Not everyone checks their tyres regularly. The first signs that your tyres are wearing can be poor handling in bad weather conditions, or taking longer to stop when you apply the brakes.
But tyre wear can be very gradual so it’s not always easy to realise that your tyre treads are disappearing. That’s why it’s a good idea to have them checked regularly by an expert. As a driver, it’s your responsibility to ensure that your tyre treads are not worn below the legal limit of 1.6 millimetres.
To make this easier to identify, tyre manufacturers mould tread wear indicators (T.W.I) into the design of the tyre’s tread pattern usually at 1.6mm. As soon as the tread is worn to the height of the tread wear indicator, the tyre has reached the legal minimum tread depth and you should replace the tyre as soon as possible.
It’s not just use that wears tyres out. Over inflating tyres can be just as damaging as forgetting to pump them up. Emergency breaking can wreck a tyre (but save your life) and not having your wheels balanced or aligned properly can shorten the life of a tyre.
