Surly Extraterrestrial Tubeless MTB Tire – 27.5×2.5 Folding Black/Slate 60tpi

The ExtraTerrestrial Touring-Hybrid Tire is engineered for riders who crave reliability without sacrificing speed across diverse terrains. Whether you’re tackling urban streets littered with debris or venturing onto gravel paths during weekend escapes, this tubeless-ready clincher delivers unmatched durability paired with smooth-rolling efficiency. Its directional tread pattern is strategically molded to grip aggressively when needed while maintaining low rolling resistance for effortless pedaling over long distances—perfect for hybrid commuters or adventure cyclists seeking all-around performance.

At its core lies advanced protective technology: a Kevlar-reinforced tread base defends against thorns and sharp objects, while sidewalls infused with nylon armor resist slashes from rocks or rough surfaces—making this tire ideal for off-road excursions where punctures are common concerns. Designed for modern setups, it’s optimized for rims between 23–30mm wide, balancing stability on pavement with adaptability on softer ground. The sleek black/slate finish adds a rugged aesthetic without compromising its functional strengths—whether you’re commuting daily or planning cross-country tours.

Why It Shines:
– Lightweight Resilience: Weighing just 1010g at labeled size 27.5 x 2.5”, it offers a featherweight build compared to bulkier touring tires while retaining robust construction through its 60 TPI casing—a blend of strength and speed rarely found in one package
– Confidence Under Pressure: Maintains optimal performance at 35 PSI—ideal for absorbing road vibrations yet firm enough to prevent pinch flats during aggressive cornering
– All-Conditions Grip: The low-profile tread channels water efficiently on wet surfaces while providing grip on loose gravel—making it versatile enough for unpredictable weather or trail conditions
