Kawada TUM04W Standard Inner Sponge Wide 4 pieces

Designed specifically for Kawada KM mini tires, this sponge inner excels on dusty and low-grip surfaces where traction is challenging. The wide profile (19mm) works alongside narrow options (14mm) to customize shoulder stiffness and cornering response. For M300GT series builds, pair softer rear compounds with firmer fronts—such as KM32 rear with KM36 front—for improved drivability. Mix and match narrow/wide configurations to refine your setup. Includes 4 pieces.
