WTB Trail Boss TCS Light 29 Mountain Tire. The WTB Trail Boss TCS Light 29 mountain tire certainly lives up to its moniker when you're out on the trails. This svelte, speed merchant of a tire sports tight enough tread spacing for full on, drag free onslaughts, yet it's blocky and tall enough to really dig in when it comes time to drop out of warp drive. A rounded profile and staggered, supported side knobs keep clamoring for traction even as the trail loses its camber. In addition to the superb tread design, there's also WTB's TCS and Light technology on board. TCS stands for Tubeless Compatible System so you can get all the performance advantages of a tubeless set up. Additionally, WTB's Light casing reduces rotating mass and contributes to a supple ride. Top to bottom, this tire will have you owning the trails like a boss.
