The GBC® Spartacus UTV / SxS Radial 8-Ply Tire excels in aggressive mud, soft terrain, and rugged trail riding!
Engineered to conquer the slickest, most unforgiving environments, the GBC Spartacus features deep lugs that provide unrelenting forward bite and high-volume clean-out in deep mud, loam, and loose earth. Square biting edges enhance tracking stability, brake control, and cornering grip across off-camber ruts and technical trails.
Despite its ferocious, mud-churning profile, the Spartacus delivers an exceptionally smooth, low-vibration ride on hardpacked trails and rocky paths thanks to its premium 8-ply rated radial (Load Range D) carcass. Backed by Greenball Tire's decades of high-performance racing heritage, this tire provides heavy-duty puncture protection and long-haul durability for demanding Side-by-Sides and utility ATVs.
