The Continental HDL2 Eco Plus (Heavy Drive Long Haul) super single drive tire, designed for fleets seeking weight savings and low rolling resistance in long-haul highway use, is scheduled for November availability in size 445/50R22.5 and will feature 27/32nds of tread depth, a closed shoulder and regenerating sipes in the middle of the tread blocks. A three-dimensional sipe in the center of each tread block couples the groove under compression to facilitate increased strength while still allowing more block flexibility as the block exits the footprint. The tire’s groove geometry is designed to reduce the stress at the groove bottom by placing the element between the two groove bottom radii; this separates the forces at each side of the groove bottom and helps reduce premature wear.
The HDL2 DL (Heavy Drive Long Haul, Deep Lug) truck tire soon will be available in size 445/50R22.5 and is designed for fleets seeking weight savings and low rolling resistance in the mixed long-distance and regional traffic application. At 27/32nds of tread depth, the super single’s tread design was copied from existing sizes and provides deep tread depth with the added traction of an open shoulder. The tire also features a bottom groove treatment that helps reduce stone retention and outside groove geometry designed to distribute stress evenly throughout the groove bottom, providing added durability.
