Traxxas 6874R Split-Spoke S1 Kumho Tires

The Traxxas 6874R is a pair of assembled, pre-glued race-compound tire and wheel units: SCT Split-Spoke satin chrome wheels with a black beadlock-style ring, licensed Kumho tires in the ultra-soft S1 off-road racing compound, and foam inserts, mounted and glued at the factory.

S1 is the softest compound Traxxas offers, conforming to surface texture more readily than standard rubber and delivering a clear step up in mechanical grip on clay, loam and medium-bite tracks. Tread life drops sharply on abrasive surfaces in exchange, so most racers save S1 sets for qualifying and mains.

The Kumho tread reproduces the full-size Kumho light-truck pattern at scale. Its blocks sit closer together than an open mud-terrain lug and cover more of the carcass, producing a larger effective contact patch — particularly effective on packed dirt, groomed clay and indoor surfaces.

Sizing is the short course dual-profile standard, 2.2 inches at the outer bead and 3.0 inches inside; the beadlock ring is molded styling rather than functional hardware. Fitment is 4WD front and rear, or 2WD rear only.

Fits: Traxxas Slash 4X4 front/rear, Slash 2WD and Slash VXL rear.

Includes: two assembled tire and wheel units with foam inserts.
