If you run 1/10 off-road buggies and want more reliable handling, the Tamiya 84201 inner sponge set provides a simple upgrade. Sized for common 60/29 and 62/35 2.2 inch tyres, these sponges help maintain consistent tyre shape during aggressive driving.
These sponges are intended for DF and DT series vehicles and work well with Dual Block style tyres and similar tread patterns. They are useful for club track sessions and rough off-road practice where sidewall support matters.
Adding an inner sponge can tighten steering feel and reduce tyre squirm under load. Properly fitted sponges distribute pressure more evenly across the tyre carcass, which can cut down on premature wear and keep lap times consistent.
