Description Description

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

Great company

The product is and always have been second to none. We will continue to use box and all of their products.

Well worth the switch

Fast and.light better for wet tracks.

Stick to anything but don't last

My 8 year old inter, now expert, ran these for three months front and rear. Packed dirt and one glued track. Once a week racing. They stick to anything, but fall apart quickly. The rear center tread is almost bald and the rear shoulders starting falling off in chunks. The front shoulder tread is worn badly. These are pro level tires meant for pro level racing where tires are changed every few races. The Box One tires have no longevity. Understand you are getting a top tier race tire that has been designed with compromises, the main one being longevity.

Great! … When they don’t fall apart

Nice tread and lightweight tires … BUT I have had 5 in the last 6 months that either bubbled like a golf ball or just completely separated along the center within days of install. It’s a coin toss if these will hold up or not and it’s not cheap to find out.
