This is part of a project I'm in. Namely different trailer for Tamiya trucks in scale 1/14. Here you get the wheels in the first place. They are made to fit Tamyia trucks as well.
There are two versions. Version 1 is tires and rims separated so the tire can be printed in flex filament and version 2 is tires and rims assembled for plain print.
Update apr. 2019:
I have added front wheels after request. There are standard front wheels with or without tire and a set of front wheels for 4WD. The tire is the same in both versions.
