Hillbilly Grid Gravity T9 TLR Enduro Tire
Hillbilly Grid Gravity T9
Enduro · Park · Downhill · Front & Rear

Hillbilly likes it raw. Built for steep, slippery, loose, and wet natural terrain — the kind that fights back. The aggressive GRIPTON T9 compound sticks everywhere, even in the greasiest conditions, while its high-damping formulation reduces tire bounce and deflection for a planted, controlled feel. Large block-in-block shoulder knobs and deep center spike knobs complete the package.

The GRID Gravity two-ply casing is the burly option in the Hillbilly lineup — designed for enduro, park, and downhill where durability and puncture protection are non-negotiable. The two-ply construction provides incredible strength and exceptional tire stability when loaded hard into corners or compressed off jump faces. Run it tubeless with sealant for the best balance of grip, protection, and performance.

  • GRIPTON T9 Compound: Extreme grip in all conditions — sticky enough for the greasiest roots and loam.
  • Large Block-in-Block Shoulders: Supported cornering under hard loads — big shoulders bite and hold.
  • Spike Center Knobs: Dig in and find traction over loose terrain, loam, and wet roots.
  • GRID Gravity 2-Ply Casing: Built for enduro, park, and DH — maximum puncture protection and stability.
  • Tubeless Ready (TLR): Mount with or without tubes, run lower pressures for better traction.
  • Front & Rear Compatible: Versatile enough for either wheel position.

Use: Enduro, park, downhill. The burly alternative to GRID Trail — heavier but more durable.

T9 — Built for the Greasiest Conditions
GRIPTON T9 is Specialized's highest-grip compound — formulated for the kind of traction that shouldn't be possible. It sticks to wet rock, greasy roots, and slick loam with a level of confidence that transforms how you ride in bad conditions. The high-damping properties also reduce the bounce and deflection that come with aggressive gravity riding, keeping the tire planted and controlled when the terrain gets rough.
Large Block-in-Block Shoulders
The large block-in-block shoulder knobs on the GRID Gravity are built to be leaned on. The outer block provides initial bite into loose soil and soft conditions, while the inner block supports the structure under compression — so when you're hammered into a wet corner or compressing off a slab, the knob doesn't fold. That support translates directly into confidence and control.
GRID Gravity 2-Ply — Built for Abuse
The two-ply GRID Gravity casing is what separates this from the GRID Trail version. Two layers of casing protection bead-to-bead means this tire can take hits, impacts, and compressions that would puncture or pinch-flat a lighter casing. Ideal for enduro stage races, park laps, and the kind of downhill runs where a flat has real consequences.
