Specialized Hillbilly Grid Gravity T9 Enduro 29" Tire Grips Where the Trail Gets Ugly When the trail turns steep, loose, and wet all at once, most tires start making compromises. The Hillbilly Grid Gravity T9 doesn't. The Deep spike center knobs claw into loose terrain to find traction where other tires spin out, and large block-in-block shoulder knobs give you the support you need when riding hard into a corner. Block-in-block transition knobs bridge the gap between center and shoulder, keeping the feel predictable across the full range of engagement. The GRIPTON T9 compound is the key ingredient here, it dampens terrain-induced chatter, rebounds slowly, and maintains extreme grip across steep, slippery, and wet trail conditions. The two-ply Grid Gravity casing backs all of that up with the stability and puncture protection this kind of riding demands.
