SPECIALIZED HILLBILLY GRID GRAVITY T9 TLR ENDURO TYRE

Maximum Grip for Wet, Loose, and Technical Terrain.

The Specialized Hillbilly GRID Gravity T9 TLR Enduro Tyre is built for riders who need uncompromising traction in steep, slippery, and unpredictable trail conditions. Designed for gravity riding, enduro racing, bike parks, and downhill terrain, the Hillbilly thrives where the trails get loose, muddy, and technical.

An aggressive tread pattern with deep centre spikes and large block-in-block shoulder knobs bites into loose soil and soft terrain to maintain control when braking and cornering. Specialized’s GRIPTON® T9 compound delivers extremely high traction while adding damping to reduce trail chatter, helping riders stay composed through roots, rocks, and rough sections.

Combined with the ultra-durable GRID Gravity two-ply casing and Tubeless Ready (TLR) construction, the Hillbilly offers outstanding stability, puncture protection, and control when riding hard in demanding conditions.

DESCRIPTION

The Specialized Hillbilly GRID Gravity T9 is engineered for aggressive mountain biking where traction and durability are essential. Its tall centre knobs dig deep into soft ground while reinforced transition knobs improve stability and rolling efficiency. Large supported shoulder blocks provide confidence when leaning into corners on loose terrain.

The Sticky Fast GRIPTON® T9 compound maximises grip in wet and slippery conditions while absorbing trail vibration for improved control. The GRID Gravity casing adds exceptional strength and sidewall support, making it ideal for riders pushing hard through rough terrain, jumps, and high-speed corners.

As a Tubeless Ready tyre, the Hillbilly can be run with sealant to reduce punctures and allow lower tyre pressures for improved traction and ride feel.
