Prepare for your inspection
How to self-check tyre treads
To save time and money, make sure your tyres meet Western Australia's safety requirements before you take your vehicle for an inspection.
Check your tyre tread depth
Place a 10 cent coin between the tread of each tyre. If you cannot see the edge of the coin, like in the bottom photo, the tyre passes the minimum requirement.
If you can see the edge of the coin, your tyres do not meet the requirement and will need to be replaced before you can get on the road.
