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

Rear insert for 1:10 buggy tyres

This Kyosho 612204B rear insert is an RC-scale closed cell foam part designed to sit inside 1:10 buggy rear tyres and support the tyre profile during use. It provides a stable internal form that helps maintain tyre shape under load and assists in repeatable setup checks on dirt and mixed-surface tracks.

Compatibility is limited to 1:10 buggy tyres where a closed cell style insert is appropriate; verify tyre internal diameter and wheel offset before fitting. The insert is presented as a tyre support component rather than a tyre or wheel; it complements tyre pressure, compound choice, and shock settings as part of overall handling setup.

Installation notes: fit the insert so it seats evenly around the rim, trim any excess only where clearly needed, and avoid adhesive or solvents that could degrade foam. Check that the bead sits correctly on the rim and run a short systems check on the bench before track use. If you remove tyres frequently, handle the insert carefully to prolong service life.

Tuning role: closed cell inserts alter how the tyre holds its profile during cornering and acceleration. Firmer support tends to preserve a flatter contact patch and quicker turn-in, while softer support can allow more local deformation and increased traction on low-grip surfaces. Use the inserts as one variable within a broader setup approach including shock rates, anti-roll balance, and tyre compound selection.

Suitable as a direct internals replacement for 1:10 buggy rear tyres that accept closed cell inserts, this part helps engineers and hobbyists fine-tune rear traction and consistency without changing wheel or tyre geometry.
