WTB Vulpine S - 2025

The Vulpine S is the fastest tire we make. Vulpine S is the latest race-focused addition to WTB’s line of beloved gravel tires. Vulpine S is the gravel revamp of a proven semi-slick mountain tread with years of swift efficiency under its belt. The slick centerline decreases rolling resistance while its round tire profile is packed with short, tightly-spaced knobs to provide predictable cornering traction on hardpack terrain.

Fastest tire we make
For racers aiming to maximize straight-line speed without sacrificing grip in the corners, Vulpine S is the perfect choice. A solid centerline delivers pure speed, while tightly packed small knobs bite into the dirt as you lean through turns.

Fastest Centerline
The smooth rolling surface of the Vulpine S reduces rolling resistance and improves tread longevity, resulting in a longer lifespan than other gravel tires.

Round Profile
Overall knob profile mimics a high-volume road tire, which provides equal cornering confidence in a variety of different terrains and conditions.

TCS Tubeless Ready
TCS (Tubeless Compatible System) is WTB's standardized tubeless rim/tire system. TCS tubeless ready compatible tires eliminate the need for tubes, reduces weight, and accommodates lower tire pressures for improved traction and comfort compared to a traditional tube-type tire.

SG Puncture Protection
WTB’s SG tires start at the material level, specifically formulated for superior sidewall protection and increased air retention in high-pressure tires

Sidewall Protection: The extra layer defends most exposed areas of the tire and improves air retention for high-pressure tires.

Dual DNA
Dual DNA rubber compound combines harder, faster-rolling center sections with softer, grippier shoulders for optimal performance and weight. Additionally, each tire is equipped with robust SG puncture protection to ensure durability and reliability on any terrain.

Zero Plastic Packaging
All new WTB tires are packaged using 100% recycled materials and zero plastic. Our engineers and marketing team are constantly working towards reducing the amount of packaging our products requiring, while still providing you with the necessary information to make an informed purchasing decision. It's no small task, but minimizing the total amount of packaging has become an integral part of product development.

This results in simplistic packaging using more recycled materials and less zip ties. In the next few years, we're working to ensure 100% of WTB packaging goes in the recycling bins.

Tried and True
Gravel racers Whitney and Zack Allison put the Vulpine S to the test during the 8-day Transcordilleras bikepacking gravel race in Colombia, as well as the grueling 200-mile Unbound Gravel in Kansas, among other events.
