Tasmania Legal Wheel Modification Rules: TAS Wheel and Tyre Guide

Tasmania follows a safety and approval-based approach to vehicle modifications. Wheel and tyre changes can be straightforward when they stay close to manufacturer options, but aggressive fitments can require closer checking.

The national technical baseline is VSB 14 Section LS: Tyres, Rims, Suspension and Steering. Tasmania's vehicle modification process should be checked before fitting a wheel package outside normal standards.

Quick Answer for Tasmania

Aftermarket wheels can be legal in Tasmania if they keep correct load and speed ratings, stay within diameter and track limits, do not rub, do not protrude beyond guards, and do not use ordinary wheel spacers.

Wheel Spacers in Tasmania

VSB 14 says wheel spacers or adaptors between the wheel mounting face and road wheel must not be used unless fitted as original equipment by the manufacturer. Tasmanian drivers should avoid spacers unless a proper approval pathway has been confirmed.

Offset and Wheel Track

Under VSB 14 guidance, passenger cars are limited to a 25 mm track increase beyond the manufacturer's maximum. Eligible off-road 4WD and goods vehicles may allow up to 50 mm.

The final result must still have guard coverage, clearance and safe steering/braking operation.

Tyre Diameter

Passenger cars are generally limited to 15 mm larger or 26 mm smaller overall diameter than a manufacturer-designated tyre. Some eligible off-road and goods vehicles may allow up to 50 mm larger diameter.

Tasmania Fitment Checklist

• Start with the tyre placard.
• Confirm tyre load index and wheel load rating.
• Calculate diameter and track change.
• Check full-lock clearance and loaded suspension travel.
• Confirm tyres sit inside guards or flares.
• Avoid spacers unless original equipment or approved.
• Confirm whether Tasmania requires inspection or approval.
