Give your tyres firmer support with Tamiya 60D inserts

The Tamiya 50686 - M-Chassis 60D Inner Sponge set supplies sturdy internal cushioning to keep M-Chassis tyres true to shape. This four-piece set supports steady contact patches and helps preserve tyre profile during aggressive driving or long practice sessions.

Exact fit for M-Chassis setups

Specifically matched to Tamiya M-Chassis tyres, these 60D sponges seat neatly inside the tyre carcass for a reliable fit. They help maintain consistent steering and traction behaviour when pushing the car on a range of surfaces.

Hardwearing foam for regular use

Built from resilient foam, the Tamiya 60D inners resist flattening and retain their firmness after repeated runs. Their durability makes them a useful part of a maintenance kit for active hobbyists and club racers.
