How Long Do Tires Last?Jul 30th, 2019
For many years, the only way to determine if tires needed to be replaced was the use the ‘penny test’, which involves sticking a penny (or a quarter) into the tread of a tire. If you can see the head of the person on the penny, your tires are too worn and the treads are too shallow, meaning that the tread depth is less than 2/32 of an inch and it’s time to replace your tires. If the top of the head on the penny is covered, it means that the treads in your tire are deep enough to continue the use of the tire and that you’ll have some time before you need to replace them. While this is a good way to tell if your tires are too worn to continue using, that’s not the only reason you might need to swap out your old tires for a brand-new set.
How Long Do Tires Last?
As a general rule of thumb, the tires on a vehicle you drive fairly often will likely last you about 3 to 5 years or approximately 75 000 – 100 000 km. The shelf life of a tire will majorly depend on how often the car is driven. The less often a vehicle is driven, the longer its tires will last. All tires expire eventually, which is why our Service Departments recommend replacing all tires once they get too old (even if they haven’t already been replaced, aren’t fully worn down, the tire is a spare, or the tires are in storage), if they haven't already been replaced for another reason. This is because as the tire gets older, the rubber starts to crack and cause parts of the tire to separate from each other.
With that being said, there’s no exact way to tell how long a tire is going to last since it almost completely depends on environmental and other external factors. This can include climate, driving habits, road conditions, and tire maintenance. For example, if you drive in extreme temperatures, speed on damaged roads, and neglect tire maintenance, your tires likely won’t last as long as the average tire would.
Signs Your Tires Need to be Replaced
Abnormal Bulges or Bumps: These bulges and bumps are most likely changing the tire’s structure and affected their ability to create traction on the road. This means they’re probably not safe to use anymore.
The Tread Wear Bar is Visible: When the tread wear bar is level with the actual tread, it means that the tread is less than 2/32 of an inch deep and that it’s time to switch out your tires. This can also be checked using the penny test we talked about earlier.
The Tire is Punctured: It’s always best to check the punctured tire immediately. If the puncture is less than six millimetres deep, it may be worth it to repair the original tire, but if the puncture is deeper than this, your best bet would be to replace the tire instead of trying to repair it.
