Hardpack gravel and mixed pavement demand a tire that doesn't waste watts on the road sections between the dirt. Specialized built the Pathfinder TLR for exactly that terrain, and the reworked tread is claimed to be 19% faster than the previous Pathfinder Pro 2BR. If your rides trend toward chip-seal roads, dry hardpack, and light gravel with the occasional loose section, this is the tread in the Specialized gravel range that leans furthest toward speed.

The tread uses a dual-density compound: a firm GRIPTON T2 compound down the center for wear resistance and straight-line velocity, and a tackier GRIPTON T5 compound on the shoulder knobs for cornering grip. The low-profile center section and tightly spaced knobs keep rolling resistance in check on tarmac, while the shoulder knobs bite when you commit to a corner. Reviewers noted the tire feels fast and snappy on tarmac and compact gravel, with the shoulders still supplying reassuring grip when the surface turns loose. It's a semi-slick approach that rewards riders who want to hold road-bike speeds until the dirt gets serious.

The casing is a 60 TPI 3-ply TLR construction with four plies under the central tread and three at the sidewalls, and Specialized claims 30% improved cut resistance over the previous generation along with a 25g weight reduction from the reworked knob layout. That's a shift from the older 120 TPI Pathfinder Pro construction — you trade some suppleness for a casing tuned for tubeless pressures and long gravel days. The tubeless-ready bead and casing let you drop pressure for comfort and traction without inviting flats, and testers running the tire between 30 and 50 psi reported reliable puncture protection over rough terrain....
