How Long Will 5mm Tyre Tread Last? Distance & Time

When did you last check your tyres’ tread?

As a car owner, you should know how long your vehicle’s tyre tread will last before a replacement is necessary.

If you’ve checked your tyres and they’ve got 5mm tread left, this guide will be helpful!

How Long Will 5mm Tyre Tread Last?

On average, you can expect a 5mm tyre tread to last for approximately 20,000 to 30,000 kilometres.

This distance estimation is based on a mix of city and highway driving conditions with regular maintenance. However, you should also keep in mind that individual driving habits and road conditions can alter this estimation.

In terms of years, you can anticipate your 5mm tyre tread to last around 3 to 4 years under typical driving conditions.

Again, this is a rough estimate and can differ based on your unique driving patterns and the frequency of maintenance.

How Often Should You Check Tyre Tread Depth?

Regularly inspecting your tyre tread depth is essential to ensure your safety on the road.

While the legal minimum tread depth in Australia is 1.5mm, it’s recommended to replace your tyres once the tread depth reaches 3mm. This provides a safety margin and allows for optimal performance under various driving conditions.

As a general rule of thumb, check your tyre tread depth at least once a month, and always before embarking on long journeys.

To measure the tread depth, you can do the coin test, use a depth gauge, or simply locate the tread wear indicator on your tyre. Refer to our guide on how to check tyre tread for more details.


With 5mm of tread left, your tyres will still last for a considerable distance, but their actual longevity depends on various factors, such as driving habits and maintenance.

Regularly check your tyre tread depth and address any issues promptly to extend the life of your tyres and enhance road safety.
