Tyre Dealers & Fitters Insurance

Tyres are the only part of a vehicle that touches the road, and incorrect tyre fitting or advice is directly linked to accidents. For tyre dealers and fitters, this creates a professional liability exposure that is unusually high relative to the apparent simplicity of the work. A single claim arising from a wheel separation or blowout linked to your fitting work can run into hundreds of thousands of dollars — making adequate professional indemnity non-negotiable.

Product Liability vs. Professional Indemnity: Understanding the Difference

Tyre businesses face two distinct liability categories that are often confused. Product liability arises from the products you sell — if a tyre has a manufacturing defect that causes a failure, the injured party can pursue you as the seller, even though the defect originated with the manufacturer. You would then typically have recourse against the manufacturer, but that process takes time and money.

Professional indemnity (sometimes called professional liability or errors and omissions cover) responds when the failure arises from your professional work — fitting a tyre of the wrong specification, undertorquing wheel nuts, fitting a tyre to a damaged or corroded wheel rim, or providing incorrect advice about tyre suitability for a vehicle's load rating. Both covers are essential; neither replaces the other.

The Wheel Nut Problem

Wheel nut undertorque is one of the most well-documented failure modes in tyre fitting. A wheel that separates from a vehicle at highway speed creates a catastrophic liability event — for the driver of the subject vehicle and for any vehicles or pedestrians struck by the detached wheel. Most claims of this nature result in serious personal injury or fatality, with corresponding claims in the hundreds of thousands of dollars.

Torque verification procedures are the standard industry defence against these claims. Many tyre fitting operations now use electronic torque verification systems and provide torque check cards to customers. From an insurance perspective, documented torque procedures reduce both the frequency of claims and the severity of the professional indemnity exposure — demonstrating that your work met the applicable standard of care.

Mobile Tyre Fitting Operations

The mobile tyre fitting market has grown significantly, with vans attending customer homes, workplaces and roadsides. Mobile operations create a different insurance structure requirement:

The van itself needs commercial motor insurance, not private motor cover. The tyre stock and fitting equipment in the van need portable goods cover. If you drive a customer's vehicle to reposition it for fitting access, you need road risk cover. And public liability must respond at customer premises, not just at a fixed workshop — ensure your policy wording doesn't restrict cover to a specific address.

TPMS and Modern Vehicle Complexity

Tyre pressure monitoring systems (TPMS) are now standard on most vehicles built since 2012. Incorrect fitting procedures can damage TPMS sensors, which are expensive to replace and, in some markets, legally required to be functional. If your fitting process damages a TPMS sensor, your professional indemnity covers the replacement cost — but having documented procedures for TPMS handling reduces the frequency of these claims.

Similarly, ADAS systems on modern vehicles are affected by wheel and tyre changes — changes in tyre rolling circumference or wheel offset can affect safety system calibration. Increasingly, tyre dealers are being asked about ADAS recalibration after fitment changes, and the professional liability implications of incorrect advice in this area are growing.
