Wheels & tires

Road wheel

Supports the tire and connects it to the hub.

Drag to turn it Open in the 3D lab
Where it sits

Bolted to each wheel hub.

How it works

Rim width, diameter, offset, load rating and fastening determine compatibility with the vehicle.

Think of it as

The rigid frame inside a rolling rubber shoe.

Symptoms when it fails

Vibration, cracks or air loss can involve the wheel, tire, hub or balance.

Lifespan

Inspect tread, age, pressure and damage rather than using appearance alone. Wheels and bearings are assessed for condition.

Repair cost

Inflation correction is small work; tire sets, forged wheels and damaged hubs can be much larger expenses.

The BMW angle

A BMW wheel that bolts on may still have unsuitable offset, load rating or brake clearance.

Used in

BMW models using the specified wheel and tire combination; approved sizes vary by vehicle.
