Box One™ 120 TPI Folding Tires were engineered with a minimalist approach to hit lofty goals for weight, traction, rolling resistance, and rebound. At its heart is a super-supple 120TPI casing where we forced in as much rubber displacing nylon as possible. Skin walls are employed to reduce drag and further reduce weight. We flanked the high-density casing with a tightly packed hoop of aramid fibers. Finally, we 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 again remove more weight. 

Note: Not a tubeless tire

Box One 120 TPI

After weekend of racing the tire has already start deteriorate. When the wheel is spun you can see the centreline of the tread expanding causing the tire to no longer run true. The kicker is this isn’t the first set of tires either. I had previously raised this up to Box with photos and didn’t receive a response. Perhaps using a different adhesive may work.
