| 1. Match wheel diameter and width | The wheel must work with the specified tire size and fit within the vehicle’s available clearance. | Confirm the wheel diameter and width against the vehicle or axle manufacturer’s specifications and the intended tire’s approved rim-width range. | Do not rely on the old wheel’s appearance alone; check the vehicle placard, service information, or original equipment specification. |
| 2. Confirm the bolt pattern | The number of mounting holes and the diameter of their circle must match the hub. | Check both the number of studs or holes and the bolt-circle diameter. For example, a 10-hole pattern is not enough information without its circle diameter. | Request the complete pattern specification and confirm it against the exact axle or vehicle configuration. |
| 3. Check wheel offset and backspacing | These dimensions affect wheel position, tire clearance, and the relationship between the wheel and suspension or body. | Verify the specified offset, usually expressed in millimetres, and any required backspacing. Confirm the reference face used for the measurement. | Compare with the approved specification; changing wheel position can create clearance or handling issues. |
| 4. Match the hub interface | The wheel’s centre opening and mounting face must seat correctly on the hub for the specified fitment. | Confirm centre-bore or hub-pilot diameter, mounting-face design, and whether the wheel is hub-piloted or stud-piloted. | Do not treat hub-piloted and stud-piloted systems as interchangeable. Check the specified fastener type and seating style as well. |
| 5. Verify load rating and application | Each wheel must be suitable for the loads imposed by the vehicle and its operating conditions. | Check the wheel’s rated load against the applicable axle loads and vehicle requirements. Also confirm tire capacity and local regulations. | Use the rating for the exact wheel specification; do not assume that wheels of the same size have the same load capacity. |
| 6. Check material, construction, and service needs | Wheel construction can affect weight, durability, maintenance, and suitability for the intended duty cycle. | Confirm whether the wheel is steel or aluminum, its construction and finish, and any maintenance or inspection requirements. | Choose based on the vehicle’s work environment, service requirements, and approved specifications rather than appearance alone. |
| 7. Confirm documentation and exact fitment | Truck specifications can vary by model year, axle, market, and configuration, so a general size match may not be sufficient. | Provide the vehicle or axle details and request a drawing or specification sheet listing size, bolt pattern, offset, hub dimensions, fasteners, and load rating. | Before ordering, confirm the final specification in writing and check any applicable import, certification, and road-use requirements. |
