WTB Resolute TCS Tubeless Tire - 650b

The WTB Resolute TCS Tubeless Tire 650b is built around a tread pattern that genuinely works across mixed terrain — the kind of riding where you move between packed gravel, loose dirt, and the odd stretch of tarmac without wanting to stop and swap wheels. Small, square knobs run in a 1-2-1-2 alternating pattern down the centre, giving you a fast, predictable roll on firm surfaces, while the open side knobs clear mud and shed debris when the ground softens. The transition from straight-line to cornering is intentional — there's no abrupt shift in feel as the tyre rolls onto its edges.

At 440g, the 650bx42 version runs lean for its size, helped by a supple casing and folding bead. TCS — WTB's Tubeless Compatible System — means it seals reliably tubeless or runs just as well with an inner tube, so your setup doesn't dictate your tyre choice. Finished with a tan sidewall, it's directional — mount with the rotation arrows pointed in the direction of travel and set your pressure to conditions.
