Utili-T Inner Tube – 27.5 × 3.00–3.50 | 48 mm Presta Valve

This Utili-T inner tube is designed for 27.5-inch (650B) wheels using very high-volume tires and a Presta valve.

It is a correct replacement tube for ISO 584 rims commonly found on plus-size and oversized 27.5-inch tire setups. The wider tube profile ensures proper expansion and fit for large-volume tires, while the 48 mm Presta valve provides adequate length for thicker or deeper rims and works with standard Presta-compatible pumps.
