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.

DUAL COMPOUND

Two compounds used within the tread of select tires to offer lower rolling resistance and increased cornering grip.
