Throughout the life of your vehicle it is highly likely your tyres will need to be replaced, but for many motorists this can be a daunting prospect. Firstly you need to know when you need new tyres and then how to choose the right tyres to suit your vehicle, driving style and budget.

How do you know when your tyres need replacing? Check the tread wear indicators


First and foremost, you need to know how to check your tyres always have at least the minimum legal tread depth limit of 1.6mm across the central three quarters and around the entire circumference. You don’t need a vehicle maintenance diploma or any special equipment do to this, just bend down and locate the Tread Wear Indicators (TWI) situated in the main grooves of your tyres. These TWI’s appear as small raised bars and if the surface of the rubber is level with these bumps it is likely your tyre is close to the legal limit. Check each tyre at several locations around the circumference to get an accurate picture.

However, it is worth pointing out that safety and motoring groups recommend you replace your tyres before they reach this stage, ideally when they wear below 3mm, in order to ensure better performance and your safety on the roads.

Your tyres should also not display any visual signs of damage, such as lumps and cracks, or irregular wear. These issues can lead to slow punctures or blow outs at high speed.


If you discover you need new tyres, your next task is to find out which ones to choose. All tyres are now accompanied by a label which assesses their performance in three key areas: wet grip, fuel efficiency and noise emission. This allows you to have a better understanding of not only how well a tyre performs, but also if it is suited to your needs, eg, if you do a lot of driving, fuel economy will be important, but so will performance, especially if you spend hours on the motorway each week.
