Ever noticed how your RC car's tires go flat or lose shape after a few hard runs? That's where these INJORA silicone rubber foam inserts come in—they're the simple fix that makes a big difference. Crafted from flexible yet tough silicone foam, these large blue inserts fit snugly inside 1.9-inch wide tires on wheels measuring 118-122mm in diameter with a 4.75-inch outer diameter.
Unlike cheap foams that compress too much or tear easily, these hold their shape run after run. The silicone material resists wear from dirt, rocks, and impacts, so you spend less time swapping parts and more time driving. They add just the right amount of cushion to absorb shocks without making your tires balloon out, keeping handling sharp whether you're on loose gravel or slick surfaces.
Picture this: You're tackling a steep rock face in your scale crawler, and instead of the tire deforming under torque, it grips firm thanks to the insert's support. Or on the dirt track, they help maintain consistent contact patches for faster laps. RC enthusiasts swear by inserts like these for extending tire life—I've seen them turn worn-out setups back into winners.
Installation is straightforward: just deflate the tire, pop out the old foam if needed, slide these in, and reinflate. No glue, no mess. They're especially great for axial, Axial, or similar 1.9-inch wheel setups common in the hobby.
If you're serious about your RC game, these foam inserts are a no-brainer addition. They deliver that pro-level consistency without the high cost, letting you focus on the fun. Stock up for all your rigs and feel the difference on your next outing.
