Tamiya 70241 Fun Sponge Tires - STEM Series Assembly Kit, Model 70241  [70241]

Investigate mechanics using Tamiya 70241 Fun Sponge Tires

The Tamiya 70241 Fun Sponge Tires provide a low-tech way to explore mechanical principles. These sponge tyres let modellers and students see how different contact shapes influence movement and traction in real time.

Shape-driven motion options

The blue sponge includes circular, cross and apostrophe shapes, each producing a clear motion signature. The cross form aids small climbs, while the apostrophe shape yields a jerky forward action useful for demonstrating intermittent propulsion concepts.

Compatibility with large-diameter Mini 4WD wheels

These sponge tyres are sized for large-diameter Mini 4WD car wheels and include optional sidewall cut-outs to alter softness. That lets you experiment with softer or firmer tyre behaviour depending on your objective.
