Yokomo YOKZCT16M 16mm Medium Foam Inner Sponge for 1/10 Off-road Tires  [YOKZCT16M]

16mm inner sponge for 1/10 off-road tires

The Yokomo YOKZCT16M is a 16mm inner sponge made for 1/10 scale off-road tyres, supplied as a medium-density insert to support tyre profile and handling adjustments. It is popular with buggy racers and club drivers who tune sidewall support and traction on loose surfaces.

Fit this medium-density insert to alter tyre shape and sidewall stiffness: a 16mm sponge changes how the tyre transfers power and reacts to suspension inputs. The foam balances resilience and conformity so it sits inside the tyre without adding external parts.

Fitting is simple: push the sponge into the tyre, centre it along the bead and remove any twists before mounting the wheel. After the first run check seating and inspect the insert for compression or damage, replacing it when it no longer maintains the tyre profile reliably.
