Printing and Assembly Tips: 

Rotation Direction: The tire has a specific rotation direction. Check the tread pattern and print left/right tires as mirror images for correct orientation.  

Connector: Designed for a 12mm hex connector, compatible with standard RC car hubs.  
Screws Required: Each tire requires 6 M2 screws and 6 M3 screws for secure installation.  

Support Settings: Add supports for the rim bead to ensure accurate shaping.  
Print Settings:  Wall Thickness: 0.8mm for a balance of flexibility and strength.  
Infill Density: 0% recommended for a soft tread, ideal for loose terrains like sand.  
slower for TPU to ensure precision

Material: Use TPU or TPE (flexible filament) for optimal flexibility and durability.

Important Note: After printing with TPU/TPE, allow the tire to fully cool before handling to prevent deformation from hand pressure.
