Specialized Hillbilly Grid Trail

This tire is specifically designed for loose, wet, and soft terrain. While it will work on hardpack, the deep, aggressive knobs are optimized to bite into mud and loam, which can feel draggy or less predictable on hard-packed dirt compared to a faster-rolling tire.

Yes, the Hillbilly Grid Trail is tubeless-ready. It is designed to be set up without an inner tube, which helps reduce weight and allows you to run lower pressures for better traction and puncture protection.

It is built for aggressive gravity riding, specifically enduro and downhill mountain biking. The high-damping GRIPTON T9 compound and reinforced casing make it ideal for steep, technical descents where grip and durability are your top priorities.

The T9 compound is a high-damping rubber, meaning it absorbs trail chatter and vibrations rather than bouncing off them. This provides a 'planted' feel that helps the tire track predictably over roots and rocks, especially in greasy or wet conditions.

No, this specific version of the Hillbilly Grid Trail is not rated for e-bike use. You should look for Specialized tires specifically designated as e-bike compatible if you are riding an electric mountain bike.

The 27.5-inch version of the Hillbilly Grid Trail weighs 985 grams. It is a robust tire built for durability, so it carries a bit more weight than a lightweight cross-country tire.
