Threads Per Inch (TPI)

The number of threads that cross through one square inch of a single ply of the tire’s casing. Lower TPI (ex. 60 TPI) gives better puncture, cut and abrasion resistance but is heavier. Higher TPI (ex. 120 TPI) conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tire. The trade off being higher TPI casings are more fragile compared to lower TPI casings.

FOLDABLE BEAD

Foldable beads also keep the tire secured to the rim but are lighter weight and easily transported. The bead is made of spun aramid fibers.
