Tamiya 40141 Inner Sponge Front 1/12 On-Road Tyre Insert  [40141]

Insert to Improve Tyre Contact

The Tamiya 40141 Inner Sponge Front is designed for 1/12 scale on-road cars to support the tyre sidewall and keep the tread in firm contact with the surface. That extra support helps reduce tyre roll during fast corners.

Calmer Cornering and Traction

Whether you are practising or racing, the sponge helps even out tyre contact so traction feels more consistent through bends, aiding smoother steering inputs and better exit grip.

Compatibility Notes

The sponge is compatible with many 1/12 on-road wheel setups and suits hobbyists who adjust tyre choice for different tracks. Make sure the insert seats properly inside the tyre for best results.
