Hillbilly Grid Trail T9 TLR Tire

What Our Gearhead® Experts Are Saying:

"I ran this tire on a notoriously slick, rooty descent after two days of rain, and it just stuck. The shoulder knobs hooked into every corner and kept the front end planted where looser tires would have slid wide. It's become my go-to when the trail turns greasy."

Wet season riding separates the confident from the cautious, and the Specialized Hillbilly Grid Trail T9 TLR Tire keeps us in the first category. Built for the kind of terrain that humbles riders — steep chutes, saturated loam, rooted fall-line descents — this tire digs in where others give up. The aggressive center knobs spike into loose dirt to find traction, while the high-volume shoulder blocks bite hard when we lean into corners.

What makes the Hillbilly feel different in greasy conditions is the damping built into the compound itself. Rather than bouncing off roots and deflecting over slick rocks, the tire settles into the terrain and holds a line. The GRID Trail casing adds structure underfoot, keeping the tire stable when we load it hard into a berm or compress through a rough, choppy chute. Tubeless-ready out of the box, it sets up easily with sealant and handles the kind of riding where pinch flats would otherwise end your day early.
