There are tracks included in Rad Sandbox or you might want to build your own with roads and streets modules. These are ready made Race Trucks you can use in your race based games.

Rad Race Truck models come as shown. No tire setup as there are dozens of pre-made wheel/rim/tire setups in Rad Sandbox. If you need tire setups you can download them free from the model download directory at writerz.net. All UV work is included, and you can use the model for any purpose you wish, personal or commercial.
