TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.
One layer of supple, gram-conscious casing conforms to the terrain to provide maximum performance, exceptional reliability and low rotational weight.
Specifically formulated to prioritize rolling efficiency while also providing dependable traction and lasting durability.
Available with SG2, which defends all surfaces of a tire by providing an uninterrupted layer of nylon puncture protection spanning from one bead to the other.

*WTB's tire pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tires for allowed pressures ranges, but may also consult wtb.com for the most up-to-date tire pressure recommendations from WTB. We calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing our minimum recommended pressure on WTB.com by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire
TCS Light tubeless tires feature one layer of casing to minimize rotational weight while simultaneously increasing the overall liveliness of a tire. Using a single layer of casing results in a gram-conscious tire that better conforms to any terrain and increases traction without the need for excessive knob heights that would reduce efficiency. Many of our TCS Light gravel tires feature SG2, which is our unique puncture protection technology that provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures.
It's nice to have options, which is why most of our gravel tires are available with either black or tan sidewalls. Traditional black sidewalls tend to blend in with the components and wheels of a bike and may look sleeker in the eyes of some riders. WTB tanwall tires blend retroesque looks with modern technology to create an iconic look that has become synonymous with high-performance gravel. Looks aside, gram counters may choose our tan tires because the compounds used to make them are slightly lighter than those used to manufacture black sidewalls.
