Kyosho 612204B - 1:10 Buggy Rear Insert (Closed Cell)  [KY-612204B]

Internal tyre support for 1:10 rear tyres

The Kyosho 612204B rear insert is a closed cell foam internal that installs inside 1:10 buggy rear tyres to stabilise the tyre profile during use. It creates a repeatable internal form helping with consistent handling and setup checks on varied surfaces.

Ensure compatibility with 1:10 buggy tyres that require closed cell internals by verifying tyre internal diameter and wheel offset prior to fitting. This product is an internal support item and should be used together with tyre pressure, compound selection, and suspension settings to refine vehicle behaviour.

Fitting advice: seat the insert evenly around the rim, only trim where clearly required, and avoid adhesives or solvents that can damage the foam. Confirm that the bead sits correctly and carry out a bench check before track use. Handle the insert carefully if you remove tyres frequently to avoid premature wear.

Setup impact: closed cell inserts influence how tyres keep their profile through corners and under power. Firmer internal support generally preserves a flatter contact patch and promotes faster turn-in, while softer support allows more local deformation and can increase traction on loose surfaces. Use insert changes as part of a wider setup strategy including shock tuning and anti-roll adjustments.

Offered as a direct internals replacement for suitable 1:10 buggy rear tyres, this insert helps hobbyists and engineers fine-tune rear traction and consistency without modifying wheel or tyre geometry.
