Heavy-Duty Silicone Wheel Set for Stronger Mini Sumo Grip

The SLT20P Silicone Wheel Pair is a steel-rimmed, high-traction wheel set made for builders who need a stronger wheel option for mini sumo robots. JSumo describes these wheels as handmade in high quality and better in traction than some well-known competing wheel options.

The wheel uses a CNC-processed steel rim with a silicone outer tire and is designed to fit 12 mm, 15 mm, and 16 mm diameter DC gearbox motors. An M4 setscrew inside the rim helps the wheel hold the motor shaft mechanically and strongly.

Why you'll love it

Technical specifications

Pinout & usage notes

Wheel choice directly affects robot traction, acceleration, and pushing behavior. The SLT20P is best used in builds where grip and secure wheel mounting are more important than reducing rotating mass.
