1/10 Truck Tire Inner Sidewall Support Adaptor (JCO2966)

Inner Sidewall Support Adapters for 1/10-Scale Truck Tires are glue-in inserts that reinforce the tire’s inner sidewall, increasing stiffness to reduce deflection under load. Once installed inside the tire carcass, they help the vehicle enter smoother arcs and maintain more consistent handling on high-traction tracks.

The four-piece rubber set is precisely shaped to match stadium-truck tire carcasses, with interlocking edges to align inside the tire body. The rubber bonds easily with glue, and the adapters work across glued, sealed, or naturally grippy surfaces to deliver a steadier, more predictable ride, especially in rough or dusty conditions.
