Heavy-Duty Silicone Wheel Set for Stronger Mini Sumo Grip
The JSumo 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.
Original JSumo product: We list this item as a distributor, so the product title now starts with JSumo for clearer brand matching.
Why choose steel-rim wheels? Heavier wheel sets can be useful in 2-wheeled mini sumo robots where traction, stability, and pushing force matter more than low mass.
Why you'll love it
- Strong traction: Designed for mini sumo pushing performance
- Steel rim construction: CNC-processed for strength and durability
- Motor compatibility: Accepts 12 mm, 15 mm, and 16 mm diameter gearbox motors
- Secure mounting: Internal M4 setscrew helps hold the shaft firmly
- Useful for 2-wheel robots: Extra wheel weight can support traction-focused builds
What you can build
The SLT20P wheel pair is ideal for mini sumo robots, traction-heavy compact robots, and custom builds where wheel grip and mechanical security are important.
Starter bundles
Pair it with compatible DC gearbox motors, a robot controller, and a competition-ready mini sumo chassis.
Recommended add-ons
Useful extras include replacement silicone tires, spare motors, robot blades, and sensors for a complete mini sumo drivetrain setup.
