This truly versatile tire feels right at home on your local singletrack. Its consistent, blocky tread minimizes rolling resistance until you hit the brakes and let the knobs do their work. Pair it with the Vigilante 2.3 up front for a superb trail combination. Looking for this proven tread pattern with a wider width and updated design? Check out the Trail Boss 2.4/2.6.

Optimal rim width inside: 20-25 mm

Application: Trail, Enduro
Surface: Loose on hard, Dirty, rocky

FUNCTIONS

Some tires are semi-slick and fast, while others are chunky and bite into the ground. The Trail Boss is somewhere in between, designed as a medium-terrain tire. The tight center knob cluster reduces rolling resistance, allowing them to dig in under braking. The tall outer knobs provide traction in the earliest stages of cornering.

- The center blocks are cut in a direction that improves traction under acceleration and braking by increasing the number of working edges that bite into the trail when you pedal or apply the brakes. The outer blocks have cuts that run parallel to the tire for better cornering traction.

The Trail Boss 2.25 features grooved knobs that maximize traction under braking, and their relatively tight spacing improves rear tire life by increasing the total surface area to counteract strong braking forces. Larger, side knobs extend beyond the tire's sidewall, protecting it from cutting during rear-wheel steering. We recommend pairing the Trail Boss 2.25 with the Vigilante 2.3 on the front.

- TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless casing that virtually eliminates punctures and allows for lower tire pressures for improved traction and comfort compared to a traditional tubed tire.

TCS Light Cassing
One layer of flexible casing adapts to the terrain to ensure maximum performance, exceptional reliability and low rotating mass.

DUAL DNA COMPOUND
Dual DNA is the perfect blend of performance, traction, and durability. The center tread has
a harder rubber compound that provides faster rolling and increased durability, while the sidewalls are made of a softer, slower-rebound rubber for improved control and grip.

Configuration: LIGHT FAST ROLLING

A harder, faster, and more efficient tread compound is used in the centerline of the tire. The sidewalls and lateral knobs are coated with a softer compound designed to be compliant yet trail-worthy.

SG2
TCS Light single-ply mountain tires are available with SG2 puncture protection. SG2 is a lightweight nylon ply that protects all areas of the tire with an additional level of puncture protection. SG2 bead-to-bead technology also improves sidewall stability and overall tire support without the added weight of a Tough (two-ply) casing. The flat nylon fibers in SG2 reduce the amount of rubber needed to fill the gaps between the fibers compared to traditional round-fiber protective plies. The increased fiber-to-rubber ratio increases puncture resistance while reducing weight and improving flexibility compared to our Tough casing. Independent laboratory testing has shown that Bead-to-bead SG2 provides 80% better sidewall protection than traditional single-ply tires without SG2.
