# Wheels

Upon importing, you will notice that the vehicle has only one wheel. This is because the game instances (re-uses) `wheel_lf` for all other wheels.

Wheel meshes do not have vertex groups but are instead rigged by a Child Of Constraint (as explained in [Drawables > Rigging](https://docs.sollumz.org/2.5/drawables.ydr/rigging#linking-bones-to-drawable-models)).

Also, wheel meshes have the `Is Wheel Mesh` property ticked under `Object Properties > Sollumz`.

That's all that's needed for setting up wheel meshes!

### Previewing the Other Wheels

In `Sollumz Tools > Fragment > Create Fragment Objects` is a tool called `Generate Wheel Instances`. This tool will create instances of the wheel, allowing you to better preview what it looks like in-game. This is useful when positioning the wheel bones.
