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.
