The AVID TRZ features a silica-enhanced all-season tread compound that remains more pliable at lower temperatures to increase cold weather traction. The compound is molded into an asymmetric tread design featuring Three Ride Zones (TRZ). The outside zone features large blocks and continuous ribs to focus dry road cornering grip, while the center zone features circumferential grooves to concentrate on water evacuation and the inner zone features lateral grooves and sipes to emphasize wintertime traction. The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon, along with a carcass that sandwiches high-density sidewall filler between polyester cord plies to blend comfortable ride qualities with predictable handling.
