2026 Specialized Hillbilly Grid Trail T9 TLR Trail Tire

Hillbilly Grid Trail T9 TLR Trail TireHillbilly Grid Trail T9Trail All-Mountain Enduro Front & RearDescriptionKey FeaturesSpecifications

The Hillbilly likes it raw. Built for steep, slippery, loose, and wet conditions in the continental north, this tire was designed to find traction where other tires give up. An aggressive tread with deep center knobs and high-volume shoulder blocks bite through loose soil when cornering, while block-in-block transition knobs reinforce the casing and enhance grip when railing through deep loom, gripping rock slabs, or charging over slippery roots.

The exclusive GRIPTON T9 compound is the secret weapon it sticks everywhere, even in the greasiest conditions, while its high-damping formulation reduces tire bounce and deflection. The result: more stability and control when the terrain fights back.

• T9 High-Damping Compound: Extreme grip in all conditions, reduces chatter and deflection for a planted feel.
• Deep Center + High-Volume Shoulders: Bite into loose soil, loam, and wet roots with confidence.
• Block-in-Block Transition Knobs: Reinforce structure and enhance traction under hard cornering loads.
• GRID Trail 60TPI Casing: Bead-to-bead protection, exceptional puncture resistance, sidewall stiffness.
• 2Bliss Ready: Tubeless-ready clincher mount and inflate with or without tubes.
• Front & Rear Compatible: Works as a front or rear tire depending on trail conditions.

Use: Trail, all-mountain, enduro. For riders who ride natural terrain steep, loose, wet, unpredictable.

T9 The Grip Compound for Greasy ConditionsGRIPTON T9 is Specialized’s stickiest compound built for the greasiest, slipperiest conditions the trail can throw at you. High-damping properties mean the tire rebounds slowly, staying glued to the ground rather than bouncing over rough terrain. Reduces deflection under cornering loads so you stay planted when the trail gets greasy.Block-in-Block Traction Under LoadThe block-in-block transition knobs are the Hillbilly’s secret for railing corners. The outer block provides the initial bite, while the inner block reinforces under compression so when you’re leaned over hard into deep loam or compressing off a rock slab, the knob maintains structure and grip instead of folding over.GRID Trail vs GRID GravityGRID Trail (shown): 60TPI, bead-to-bead protection, excellent for aggressive trail and all-mountain riding. GRID Gravity (available separately): Two-ply burly construction for extreme DH and enduro abuse, maximum puncture protection and tire stability when loaded hard into corners and jump faces.GeneralModelHillbilly Grid Trail T9 TLRPositionFront & RearUseTrail, All-Mountain, EnduroTerrainSteep, loose, wet, slippery natural terrainTypeTubeless Ready (TLR / 2Bliss Ready)Tread & CompoundCompoundGRIPTON T9 high-dampingTread DesignDeep center knobs, high-volume shoulder blocks, block-in-block transition knobsCasing60TPI GRID Trail bead-to-bead protection, sidewall stiffnessGRID Trail Weights & Pressures27.5 x 2.4″985g29 x 2.4″1070gRecommended PSI2550 psiAlso AvailableGRID GravityBurly two-ply construction for extreme DH and enduro conditions.
