Tamiya 50686 M-Chassis 60D Inner Sponge Set - M-Chassis tyre tuning kit  [50686]

Stabilise your tyre behaviour with Tamiya 60D foam

The Tamiya 50686 - M-Chassis 60D Inner Sponge pack gives internal support to M-Chassis tyres, helping them keep shape under load. Supplied as four sponge inserts, this set is handy for preserving tyre profile and improving predictable handling during fast laps or practice runs.

Designed for M-Chassis tyre compatibility

These 60D inner sponges are tailored for Tamiya M-Chassis tyres and slot in cleanly to provide a tight internal fit. They help the tyre maintain consistent contact and reduce irregular wear when running on smooth or technical layouts.

Robust foam for repeated use

Made from durable foam material, the Tamiya 60D inners resist breakdown and keep their firmness through multiple sessions. Their longevity makes them suitable for racers and hobby drivers who expect repeatable performance without frequent replacement.
