FORT MILL, S.C. (May 9, 2012)—Continental Tire the Americas L.L.C. has added Eco Plus compounding to its new medium radial truck HSL2 highway steer tire and is converting the entire line's portfolio to the technology.
Conti said its Commercial Vehicle Tire business unit's phasing out of the old HSL2 tire models should be concluded by the end of summer and all sizes of the new tires will have Eco Plus, which features low rolling resistance for better fuel savings.
Brand Manager Libor Heger said “even wear is crucial, if a fleet is looking for optimal steer tire performance. With the latest generation of low rolling resistance compounding, the new HSL2 Eco Plus offers not only SmartWay verified fuel saving performance, but also advanced wear characteristics.”
The HSL2 Eco Plus brings a number of features of the previous generation product's performance, he said, including increased tread wear volume. The tires have been engineered specifically for balanced pressure distribution and vectored forces within the tire's footprint, according to Heger. Continental's VAI—a graduated system of sipes that provide a visual indication of proper alignment—also is included from the previous generation product.
But the Eco Plus tread compounding, specially formulated for low rolling resistance, and footprint modifications are what Conti engineers have incorporated in the new tire to guard against irregular wear, he added.
“Components of the Eco Plus compound were specifically selected to reduce two major concerns with steer tires: decoupler groove cracking and micro-cracking in the sipes. Both of these contribute to irregular wear and premature removal of the tire,” he said.
