The Vittoria Bomboloni TNT 27. 5 Plus Tire brings inspiration from the auto industry to drive your snow bike adventures. With square stepped ramps and squared off edges, this tire looks like a miniature version of a beefy auto snow tire and digs in for grip on slippery, packed surfaces. An alternating center tread rolls fast, and strategic sipe angling provides grip on uneven surfaces such as rocks, roots, or the occasional chunk of extra hard packed snow. The Bomboloni utilizes a dual compound rubber for the ideal mix of durability and grip, with a plush 120 TPI casing for a smooth, supple ride.
