Mini-Z MB-010 Inner Tire Insert for Optima Fitment - MBW004 by Kyosho  [KY-MBW004]

Kyosho MBW004 Inner Sponge (Optima): Foam insert for Mini-Z MB-010 tyre support

Platform compatibility

The MBW004 inner fits Optima-style tyres on Mini-Z MB-010 chassis wheel assemblies. As a component replacement, it aims to preserve the intended internal support and tyre profile used on these compact off-road buggies.

Materials and build

Fabricated from a compliant foam, the insert is sized to sit between tyre and wheel on Mini-Z MB-010 assemblies. Its compressibility and section profile are selected to match the original geometry so that tyre seating and contour remain consistent.

Functional role

Its purpose is simple: support the tyre carcass to maintain nominal shape during running and prevent seating drift. In small-scale models, inner inserts influence ride feel by holding the tyre profile steady through maneuvers.

Who should buy this

Collectors and hobbyists maintaining Mini-Z MB-010 machines who require correct-fit replacement internals will find the MBW004 appropriate; it is targeted at preservation of original spec rather than performance upgrades.

The Kyosho MBW004 inner sponge is intended to maintain original fit and tyre shape for Mini-Z MB-010 applications, offering repeatable support for running and storage.
