Tamiya 53156 Hard Inner Sponge OP-156 - Tough inner for 1/10 on-road tyres  [53156]

Get Sharper Handling with Tamiya Hard Inner Sponge

The Tamiya 53156 Hard Inner Sponge OP-156 is an effective internal insert for 1/10 on-road tyres. Its firmer foam supports the tyre carcass so the tyre keeps form under load, which helps maintain predictable grip through turns.

Performance Reasons to Fit a Hard Insert

Increasing internal stiffness reduces tyre deformation during braking and cornering. Drivers often report cleaner turn-in and steadier exits when using a hard inner as part of their setup tuning.

Fitment Guide and Compatibility

Designed to suit a range of 1/10 on-road tyre sizes, the sponge slips into most tyres with basic care. Minimal trimming or adjustment is needed for common wheel widths and tyre profiles.
