Wheel Generator is a Blender addon focused on generating wheels, tires and disks. It handles shape and size adjustment, and each wheel is built from more than a hundred parameters, which produces a range of different variants.
Alongside the geometry, it includes a procedural shader with settings that vary for different conditions. You can save single or multiple wheels within a scene, each carrying its own geometry and shader parameters. It installs like any standard Blender addon, and the developer supplies documentation, a Getting Started video and a demo video.
The addon supports Blender 2.93 through 4.0 and is distributed under the GPL license. Its creator has noted that it is no longer supported or updated, and two behaviours are documented: pressing ctrl+z immediately after generation can crash Blender, and the Apply changes action sometimes fails on the first attempt. Saving your scene regularly is the recommended precaution. It sits at rank 1184 in the superhive library.
