One truck, three badges — and this is the wheel for all of them. River Hobby builds the 1/10 monster truck that sells as the Sword MT under the River Hobby and VRX banners and as the FTX Carnage in the FTX range, so this genuine factory wheel and tyre pair fits the lot: if the bag says River Hobby and your truck says FTX, that's not a compatibility gamble — it's the same manufacturer, and RH-10138W is the same part FTX lists as FTX-6310W. Aggressive monster truck tread at 119mm overall on a 59mm width, pre-mounted on white 12mm hex rims for the truck's white-wheel colourway.

A Pair, Not a Full Set

This is a pair — two complete wheels — matching the platform's front/rear pairing convention. Re-shoeing the whole truck? Order two pairs. Running the black-wheel look instead? The same wheel in black is RH-10138B (FTX-6310).

Fitment

Fits the River Hobby / VRX Sword MT and the FTX Carnage family — the shared 1/10 4WD monster truck platform — on the standard 12mm wheel hex. If you're cross-checking from an FTX manual, the exploded parts view will show FTX-6310W; from a River Hobby or VRX manual, RH-10138W. Same wheel, two catalogues. And at a full 119mm overall diameter, check arch and steering clearance before fitting to anything outside the platform — this is big rubber.

Factory Rubber, Factory Fit

Genuine replacement rubber means the tread, compound and carcass match what the truck was tuned around — no guessing whether an aftermarket tyre's diameter will bind the arches or gear the truck wrong. Straight swap, factory behaviour, fresh grip.
