When do you need to replace your tyres? Well, preferably before they become dangerous! Worn out tyres affect your braking, handling, grip and fuel efficiency, so it’s important to keep an eye on them to make sure your vehicle has a set of competent (and legal) tyres. But how can you tell when it’s time to replace your tyres?

First of all, look at your tread. This is the pattern on the surface of your tyres, and in between these grooves are ‘tread wear bars’. When these bars are flush with the tread of your tyres, they need replacing.

In the UK, the legal requirement for tread depth is more than 1.6mm across the central three-quarters of the tread, around the entire circumference of the tyre. Many manufacturers, however, advise replacement tyres at around 3mm to ensure you are getting the best performance from your tyres. Reduced tread means reduced grip and makes your car more prone to skidding and slow braking, especially on wet or slippery roads.

You could be awarded 3 penalty points and a fine of up to £2,500 per tyre if you are found with tyres outside the legal limits!

When replacing your tyres, consider buying tyres online, as you can certainly save money on a set of tyres, and even get your new tyres fitted the same day, or via mobile fitting van. It’s also a good idea when replacing tyres to check your wheel alignment and wheel balancing. If a vehicle is out of alignment, you’ll find that tyres may wear unevenly, or one tyre will wear down faster than the others. It’s best to change all four of your tyres at once to avoid this, too.

Finally, keeping your tyres well inflated (be sure to check your user manual and take into account the season when doing this) will increase their life, and improve the fuel efficiency of your car.
