Understand the wheel

Wheel Knowledge

A practical reference for dimensions, materials, construction and care. The project specification always takes precedence over general guidance.

Wheel Knowledge / Mechanical & FEA Lab

Where form meets mechanics.

Explore load paths, geometry, clearances and simulation as connected parts of a wheel-development brief. These examples explain principles; they do not approve a design or vehicle fitment.

Illustrative wheel CAD and FEA workflowILLUSTRATIVE EXAMPLE — NO PASS / FAIL RESULT
Diameter+

The nominal wheel diameter at the tyre bead-seat, expressed in inches. It is not the outer edge-to-edge measurement.

Width+

The nominal distance between the tyre bead seats. Overall wheel width is greater and must not be substituted for it.

Offset / ET+

The distance between the wheel centreline and the hub-mounting face. Positive offset places the mounting face toward the wheel's outer side.

PCD / bolt circle+

The diameter of the circle through the centres of the wheel-bolt or stud holes, stated together with their number, for example 5 × 112.

Centre bore+

The centre opening that locates around the vehicle hub. Its diameter and the hub-centric interface must match the specified system.

Load rating+

The maximum load assigned to the exact wheel specification under its documented conditions. It must be adequate for the vehicle and application.

Rolling circumference+

The distance the tyre travels in one revolution under defined conditions. It depends on the actual tyre, not the wheel diameter alone.

Clearance+

Brake, suspension, body, tyre, steering and deflection clearances must be considered together and physically verified where required.

Materials without shortcuts

The familiar words still need a precise project definition.

These explanations establish a useful starting point. They do not replace a material record, drawing, calculation, test or approved order basis.

01

Aluminium is a material family

The word aluminium does not identify one exact wheel material. Alloy, blank, forming route, heat treatment, machining basis and documentation must be defined for the individual project.

02

Forged describes a forming route

Forging and aluminium are not competing terms. A forged wheel starts from a metal blank that has been formed before machining; the exact route and evidence still belong to the project record.

03

Magnesium is a specialist material route

Material, corrosion protection, use, production capability and verification must be established before a magnesium direction can move beyond exploration.

04

Carbon hybrid needs interface evidence

A hybrid concept joins different material systems. Architecture, interfaces, loading, manufacturing control and the required evidence must be defined before it can be treated as buildable.

General care / preliminary

Care for the finish you actually have.

General advice is intentionally conservative. The wheel's own finish, construction, hardware and supplied care instruction decide the final method.

01

Start cool and gentle

Let the wheel cool, remove loose contamination carefully and avoid making an unverified chemical or abrasive method the first choice.

02

Use the instruction for the finish

Painted, polished, anodised, brushed and otherwise treated surfaces may require different care. The supplied finish-specific instruction controls.

03

Rinse, dry and inspect

Do not leave residues in details or around hardware. Dry with a clean, suitable material and inspect for damage, coating change or loose components.

04

Stop when something looks wrong

Damage, corrosion, impact, a coating change or a suspected loose component calls for project-specific assessment rather than stronger cleaning.
