For fans of routes involving as much smooth tarmac as forgotten chip-seal roads, the WTB Expanse tire keeps us rolling when we turn a new direction from that familiar intersection. The Expanse the new name for WTB's Exposure tire, which we came to know and love for its all-road use. This new version has been shored-up and is made only in a 32mm, the sweet spot for speed versus comfort. The smoother center tread lessens rolling resistance for better speed, while the file tread outer helps with cornering and stability on mixed terrain. WTB's tubeless casing uses a multilayered construction for a smooth ride that is durable even through rough conditions.
