The JSumo JS4311 Aluminum Silicone Wheel Set is a slim, high-grip wheel pair made for compact robots that need a bigger wheel diameter without too much width. With a machined aluminum hub and soft silicone tire, this wheel set is a great fit for mini sumo robots, line follower robots, and other lightweight robot builds that need clean grip and smooth rolling.

JSumo describes this as one of its thinnest wheel options for mini sumo and line follower use. That makes it a smart choice for robots where space is tight, weight matters, and you still want good traction on the floor.

Original JSumo product: We list this item as a distributor, so the product title now starts with JSumo for clearer brand matching.

Why builders choose this wheel set

  • Thin wheel profile: Easier to fit into compact robot builds.
  • Large diameter for its width: Good balance of clearance, speed feel, and slim size.
  • High traction silicone: Soft tire helps improve grip on smooth surfaces.
  • Machined aluminum hub: Stronger and more stable than basic plastic wheel hubs.
  • Secure shaft fit: M4 tapped setscrew helps hold the wheel firmly in place.

What you can build

This wheel set is ideal for mini sumo robot builds, line follower robots, and other light drive platforms where a narrow wheel helps with chassis layout and turning response.

It also works well for custom robot projects, student competition builds, and prototype platforms that need a slim but grippy wheel with a clean mechanical fit.

Fitment & shaft notes

Because this is a thin wheel design, it is especially useful where chassis space is limited or where you want a slimmer contact profile.
