SummaryThese friction tires will hopefully give a better grip... Print using 0.2mm layers. I have included lots of versions with differently sized "loops" so that you can create your own preferred grip depending on your filament/speed etc. ( In the pics I have used ETPU http://rubber3dprinting.com/ ) Use the rims found here: http://www.thingiverse.com/thing:1103751 This snap-on design is also available for tires/rims that can be used with the OpenR/C Touring Car or similar RC cars naturally.
