Alloy-wheel fitment: check before you buy

The right wheels need to suit your vehicle, not just its look. Start with the exact make, model, year and variant, then confirm the specifications below with us. Brake upgrades, suspension changes and previous modifications can affect fitment.

Bolt pattern / pitch circle diameter (PCD)

PCD describes the number of mounting holes and the diameter of the circle through their centres. For example, 5 × 114.3 means five holes on a 114.3 mm circle. Confirm both values against your vehicle specifications; the same number of studs does not mean the wheels fit. Have the fitter check the correct wheel nuts or bolts, seat type and engagement. Do not force an incorrect pattern to fit.

Offset (ET) and clearance

Offset is the distance in millimetres between the wheel centreline and its hub-mounting face. At the same wheel width, a lower offset generally moves the wheel outward and a higher offset inward. Width and offset must be checked together. Ask your fitter to confirm brake-caliper, suspension and body clearance through full steering lock and suspension travel, plus suitable tyre coverage. Do not assume spacers or adaptors are a safe or certification-free fix.

Centre bore / hub bore

The centre bore is the opening in the middle of the wheel that fits over the vehicle hub. Confirm its diameter and the wheel manufacturer's locating requirements. A smaller bore will not fit over a larger hub; a larger bore may require correctly specified hub-centric rings where approved for that wheel and vehicle. Rings do not correct an unsuitable PCD or offset. Have a qualified fitter confirm that the wheel seats correctly and uses suitable mounting hardware.

Tyre size, load rating and speed rating

Choose a tyre size approved for the wheel's diameter and width, with suitable overall rolling diameter and clearance for the vehicle. Changing wheel diameter does not mean keeping the same tyre profile. Confirm wheel and tyre load capacity for the vehicle and axle loads, and a tyre speed rating suitable for the vehicle. Ask your fitter to check manufacturer requirements, including any front-to-rear size differences or AWD rolling-circumference limits. A wheel that bolts on is not necessarily a compatible wheel-and-tyre package.

New Zealand WoF and LVV certification

Some wheel and tyre changes may require low-volume-vehicle (LVV) certification before a warrant of fitness (WoF) can be issued. Waka Kotahi's Vehicle Inspection Requirements Manual lists conditions for modifications that do not require LVV certification. For wheels, these include an appropriate fitment recognised by the wheel manufacturer, a known and reputable brand, no wheel modification, no spacers or adaptors, and suitable load capacity. All applicable conditions must be considered, not just wheel diameter.

If you are considering spacers, adaptors, modified wheels, a substantial tyre-size change ( over 5% ) or associated suspension/body changes, check the proposed setup with a WoF inspector or LVV certifier before purchasing or fitting. Certification requirements depend on the vehicle and the complete modification. This guide is a starting point, not a guarantee of fitment, certification exemption or a WoF pass.

Official reference: Waka Kotahi: Tyres and wheels, including Table 10-1-1 on LVV certification exclusions. Refer to the current guidance and confirm how it applies to your vehicle.
