Are Stretched Tyres Legal In Australia? What's The Law Say?

Are stretched tyres a fashion statement or a legal concern?

If you’re a car enthusiast or a regular driver, you’ve likely heard of stretched tyres.

This article will delve into what stretched tyres are, whether they are legal in Australia, and the associated risks.

Let’s explore this unique automotive trend and understand its legal implications.

What Are Stretched Tyres?

Stretched tyres are regular tyres that have been mounted on rims wider than the recommended width. This creates a stretched appearance where the tyre sidewall is pulled tight over the rim.

This trend is popular among car enthusiasts looking to achieve a specific aesthetic, making their cars stand out. While it may look visually appealing to some, there are important legal considerations.

The legality of stretched tyres in Australia is a complex issue.

The Australian Design Rules (ADRs) do not explicitly mention stretched tyres. However, they state that tyres must be fitted following the manufacturer’s instructions.

If a tyre manufacturer advises against fitting a specific tyre to a particular rim width, doing so is considered illegal.

Tyres used on vehicles must also meet the construction standards outlined in ADR 23. If a driver is caught using stretched tyres in Australia, they can be issued a defect notice.

This notice is not only inconvenient but also costly, as it often requires the driver to rectify the issue by replacing the non-compliant tyres with ones that meet the legal requirements.

Risks Associated With Stretched Tyres

Increased Risk of Tyre Failure

Stretched tyres are more prone to failures such as blowouts and punctures. The reduced sidewall height compromises their ability to absorb impact, making them less resilient on rough or uneven roads.

Reduced Handling and Braking Performance

The stretched design alters the tyre’s contact patch with the road, negatively affecting your car’s handling and braking capabilities. This can result in reduced control, especially in emergency situations.

Increased Risk of Aquaplaning

Stretched tyres may struggle to disperse water effectively, increasing the risk of aquaplaning in wet conditions. This can lead to a loss of control and accidents.

Tyre Sidewall Damage

The constant stretching and stress on the sidewall can cause premature wear and damage. This can lead to air leakage and tyre blowouts.

Damage to the Wheel Rim

The excessive tension from stretched tyres can put additional strain on the wheel rim, potentially leading to deformation or cracks. This not only affects the tyre’s performance but also poses safety risks.


While stretched tyres may offer a unique aesthetic appeal, they come with significant risks and potential legal consequences in Australia.

Always consult with professionals who are knowledgeable about automotive regulations and safety standards to ensure that your car remains both stylish and legal on Australian roads.
