Driving with older tyres that need replacing can put your safety at risk as well as the safety of those around you. It’s important to keep an eye on your tyres and make sure that you know the signs they may need to be replaced before the worst can happen.

Tread Wear

The treads on your tyres help your car grip the road. This is especially important if you are driving in adverse weather conditions like rain or snow. When the road is wet or slippery and you need to stop, the treads allow you to do that. If your treads are worn down, that extra grip is gone and you can have a difficult time stopping. Not only is worn tread a safety issue, but it is also a legal one. Once a tread is worn down too much, it is no longer legal to drive your car with those tyres. Each region is different, so check with your local transportation department to find out what the legal limit is.

All tyres come with something called a tread wear bar. This is a small horizontal bridge that are between your treads at a lower depth. When your tyres wear and these bars become flush with the tread, they need to be replaced immediately. Make sure that you check your treads often to ensure they are safe and legal.

Tyre Irregularities

If your tyres are showing any signs of irregular wear, it is important for you to have them inspected. This could be a small bulge in the side of the tire or worn spots on just one side. If your tyres are unevenly wearing down, it may mean that you just need a tire rotation. It could also mean a misalignment that can be easily fixed. If it isn’t fixed before more damage is done, or if there are bulges in the tyres, it definitely means that it is time to replace them.


Tyres need replacing every 6 years regardless of wear. If you look at the 4 digit code on the wall of the tire, you will be able to tell what the age of your tyres are. The first two numbers represent the week it was made and the last two numbers are the year. Check what that date is and set a reminder for yourself. Although tyres can last for up to 10 years, 6 years is the peak amount of time you should be driving on them. After that, a number of issues can arise and it can become dangerous.

If you are unsure if you should replace your tyres or not, bring your car into the professionals for an inspection. They will be able to easily tell if you still have some time left in your tyres or if you are putting your safety at risk.
