Continental introduces new truck tire line for reduced mileage costs and CO2; innovative tread and new rubber compound
Continental has introduced a new line of truck tires that offer reduced fuel consumption and improved mileage. The Conti EcoRegional HS3 and HD3 are produced using a new manufacturing process in combination with an innovative tread design for the steering axle and a rubber compound that is optimized for rolling resistance for the drive axle.
No sacrifices have been made in terms of the other significant tire properties such as mileage, robustness and traction. The Continental developers have been particularly successful in balancing the trade-off between mileage on the one hand, and rolling resistance and fuel efficiency on the other.
The Conti EcoRegional HS3, which was produced using the new Conti Diamond Technique production process, features an optimized tread surface pattern in the ground contact area with a modified tread groove geometry, reduced sipe width, and W-tread groove technology for particularly even abrasion. Together with a highly stable configuration of the circumferential longitudinal tread grooves, this enables greater mileage while also reducing fuel consumption.
The use of sipes in the newly designed tread ribs provides additional grip edges that are important for the traction characteristics. The Conti EcoRegional HD3 runs with the tried-and-tested tread concept of the Conti Hybrid Gen 3 line, but uses a new, innovative tread compound in the form of Conti InterLock Technology. It enables an unprecedented level of low rolling resistance with the same mileage, especially in regional and highway applications.
The design of the tread with “cap” (responsible for adhesion, abrasion resistance, and directional stability) and “base” (rolling resistance and damping) allows the individual zones to be optimized for specific tasks, thereby helping to resolve the trade-off. In both products, Conti EcoRegional HS3 and HD3, base compounds optimized for rolling resistance are used. In addition, rubber compounds optimized for rolling resistance are used in the casing.
