Picture this: you're ripping around the track, hitting whoops and corners at full throttle, but your tires start to balloon out, throwing off your line and costing you seconds. It's a common headache for 1/10 scale RC enthusiasts running 1.9-inch tires. These INJORA silicone rubber foam inserts fix that right away, slipping perfectly into 118-122mm diameter wheels with a 4.75-inch outer edge.
Made from high-quality silicone rubber, they're soft enough to absorb impacts yet firm enough to hold tire shape under extreme g-forces. No more wobbly handling or premature wear—the blue foam maintains consistent sidewall stiffness, so your car plants tires exactly where you point it. At the large size, they match popular tire brands without trimming, saving you setup time.
I've swapped these into my buggy setup before a club race, and the difference was night and day—sharper cornering, better jump landings, and tires that lasted twice as long. Whether you're tuning a 2WD stadium truck for tight tracks or a 4WD truggy for high-speed ovals, these inserts deliver predictable grip. They shine in hot summer sessions too, staying pliable without melting down.
Installation is a breeze: deflate the tire, pop in the foam, reinflate to spec. Pair them with your favorite INJORA tires for a matched setup that punches above its weight. RC hobbyists swear by them for dialing in suspension feel without messing with springs or shocks.
Don't let soft tires hold you back next time out. These inserts are the simple tweak that turns good runs into winning ones, keeping your RC car glued to the surface lap after lap. Perfect for racers, bashers, and anyone who hates pit stops for tire swaps.
