Push the standards of all-mountain freeride tires with the beefed-up BFT from CST. The BFT (Big Fat Tire) has it where it counts – meaty center and side knobs to dig in on tight turns and tough climbs. Available with wire or folding bead with EPS (Exceptional Puncture Safety) puncture protection. Exceptional Puncture Safety (EPS) offers an added layer of proprietary rubberized poly-fiber material between the tread and the casing. The tight weave of this lightweight, puncture-resistant layer prevents foreign objects from penetrating the casing and damaging the tube.
