RC Tyre Foam Inserts for Cars & Trucks

Get the most from your RC tyres with quality foam inserts. The right insert supports the carcass, maintains a consistent contact patch and resists deformation under acceleration, cornering and landings. We stock open- and closed-cell options in soft, medium and firm densities for 1/10 and 1/8 buggies, trucks, truggies, short course and crawlers.

Choose softer foams for low-grip surfaces and lighter cars; medium/firm for high-grip tracks, heavier vehicles or high-speed running. Closed-cell inserts offer stable sidewalls and longevity, while open-cell provides a more compliant feel. Always match insert size to tyre and wheel width for best fit; replace tired, compressed foams to restore performance.

Our range includes race-proven picks from Schumacher and Cragg Racing, durable options from HPI, plus favourites from ProLine and Jetko. Filter by vehicle scale, width and compound to find the perfect set.

Ordering is easy with large stocks on the shelf and next-day delivery options available across the UK. Need advice? Our friendly, knowledgeable team are on hand to help you choose the ideal foam for your setup. Tip: vent tyres appropriately and seat beads evenly when gluing to prevent ballooning and improve balance.
