Wheels and tyres

Last updated 01/06/2020

Keeping your wheels and tyres in tip top condition is the best way to guarantee safe driving in all kinds of conditions.


Requirements for all tyres

Strict design standards have been progressively introduced to specify everything from wheel rims that will stop a deflated tyre from coming off the wheel, to strength, air pressures, speed ratings and allowable combinations of wheel and tyre sizes. Some standard guidelines include:

  • Tyres must have a tread pattern of at least 1.5 millimetres deep in the band that runs continuously around the entire circumference of the tyre
  • Tyres must be free of any apparent defects that render the vehicle unsafe

Generally speaking, for your tyres to be legal in Australia they can be constructed using cross-play, bias-play or radial-play, but they must meet the following testing standards:

  • Resistance to bead unseating
  • High-speed performance
  • Have no ‘chunking’ (where chunks of tread break away)
  • Have no tread separation
  • Have no ply separation
  • Have no cord separation
  • Have no belt separation
  • Have no bead separation

Asymmetrical tyres also need clear indication of which side has to face outwards, and all tyres are required to have four evenly spaced wear indicators that show when the tyre’s tread has worn down to 1.6mm; anything less than that is not road-worthy.


Replacement tyres

When you’re replacing your car’s tyres, the new tyres must have a load rating equal to, or better than, the minimum load rating stated by the vehicle manufacturer on the tyre placard.

There’s also a minimum requirement relating to the tyre’s speed rating. In NSW that’s 140km/h; in other states and territories it’s 180km/h for passenger cars, 140km/ for off-road vehicles and 120km/ for other vehicles.


Tyre placards

Since 1973, all cars have been fitted with a tyre placard (usually located inside the driver's door, glove box or fuel filler cap), which specifies recommended air pressure, load capacity and speed rating of tyres. It also includes the manufacturer’s name, the date of manufacture, the type of construction and the maximum load rating.
