Your tyres are the only point of contact between your vehicle and the road, so keeping them in good condition is essential for safety, performance, and fuel efficiency. One of the most important things you can check regularly is your tyre tread depth. Worn tyres can reduce grip, increase stopping distances, and make driving in wet conditions dangerous.

At A1 Precision Automotive , we’re committed to helping you stay safe on the road. Here’s a simple guide on how to check your tyre tread and when it’s time for a replacement.

Tyre tread plays a critical role in maintaining traction, especially in wet conditions. The grooves in your tyres are designed to channel water away from the contact patch, reducing the risk of aquaplaning.

Handling and cornering become less stable

Wet weather driving becomes significantly more dangerous

In Australia, the legal minimum tread depth is 1.5mm, but safety experts recommend replacing tyres well before reaching this limit.

Most modern tyres have built-in tread wear indicators. These are small raised bars located within the grooves of the tyre. How to check:

Look for small markers on the tyre sidewall (often marked “TWI”)

Find the corresponding bar inside the tread groove

If the tread is level with the indicator, your tyre is worn out and needs replacing

This is a quick and easy method you can do at home. Steps:

Insert a 20-cent coin into the tread grooves

If the tread doesn’t reach the platypus bill, your tyres may be too worn

It’s not as precise as a gauge, but it’s a good quick check.

For the most accurate reading, use a tread depth gauge. How to use:

If your tread is getting close to 2–3mm, it’s time to start planning a replacement.

The inner and outer edges (uneven wear can indicate alignment or suspension issues)

Uneven tread wear can be a sign of underlying mechanical problems, which should be addressed early to avoid bigger repair costs.

In addition to low tread depth, look out for:

If you notice any of these, it’s best to have your tyres inspected by a professional.

Checking your tyre tread only takes a few minutes but can make a big difference in your safety on the road. Regular inspections also help extend the life of your tyres and improve your vehicle’s overall performance.
