Here is my simple original Rim for the brilliant OpenRC F1 car by Barspin.
It is made for the original Tamiya rubber Tires. -> fits perfect (Picture 1)
The original one from Barspin was to loose for mine. -> (Picture 2)
If you use the Differential from tahustvedt, just use the "Rear_Rim_F104_Tire_for_Differential.stl"

After a few Comments I added a bit on the Rear Rims, so that they fit better.
Added the Fusion 360 Files, that everybody can adjust the Rim Sizes perfectly.
Rear_Rim_F104 --> Fixed the position of the Tire Holder
All Rims --> Added 0,05mm for a better fitting
