Box One™ 120 TPI Folding Tires were engineered with a minimalist approach. Aimed to hit lofty goals for weight, traction, rolling resistance, and rebound. At its heart is a super-supple 120TPI casing where Box forced in as much rubber displacing nylon as possible. Skin walls are employed to reduce drag and further reduce weight. Box also flanked the high-density casing with a tightly packed hoop of aramid fibers. Finally, they draped this all with BMX race-specific tread that transitions from a center band with a large contact patch to unidirectional tactile knobbies on the sides. This aggressive combination allows for maximum traction out of the gate, immense adhesion in the corners, and low rolling resistance in the straights. A state-of-the-art mixture of compounds is used in various areas of the apex, wall, bead seat, and center – with higher silica content in the tread to remove more weight.
