Tamiya 70241 Fun Sponge Tires - Creative STEM Experiment Kit  [70241]

Make experiments move with Tamiya 70241 Fun Sponge Tires

The Tamiya 70241 Fun Sponge Tires kit is designed to give makers and educators a playful way to study movement. The sponge components let you test grip, rhythm and obstacle response without complex tooling.

Three sponge geometries for different behaviours

The blue sponge sheet yields circular, cross and apostrophe shapes that each influence motion differently. The cross section helps with small climbs, while the apostrophe type produces a staccato forward motion, giving clear examples of shape-driven dynamics.

Designed for Mini 4WD large wheels with tuneable softness

These tyres are made to work with large-diameter Mini 4WD wheels and include optional cut-away sidewall areas so you can soften the tyre contact. That makes them useful for testing how softness affects traction and responsiveness.
