LOUSVILLE, KY. — A new deep lug drive tire from Continental Tire the Americas has been verified for low rolling resistance from the U.S. Environmental Protection Agency (EPA), according to Continental officials on site at the 2010 Mid-America Trucking Show in Louisville, Ky., last month.
A new, low rolling resistance version of Continental’s deep lug drive tire, the HDL2 DL Eco Plus, will be released for sales in June and has already been added to the EPA SmartWay Transport Partnership’s list of verified low rolling resistance truck tires, said Clif Armstrong, director of commercial vehicle tire marketing for Continental-the Americas.
The HDL2 DL Eco Plus (Heavy Drive Long Haul Deep Lug) is designed to provide long original mileage with the industry’s deepest tread offering, a full inch (32/32nds), Armstrong said, noting that the tire also sports a closed shoulder tread design that provides excellent traction in both wet and dry road conditions and resists irregular wear.
Its innovative lug angle provides outstanding traction throughout the life of the original tire, and a wider casing increases handling stability, he said.
Not only is the new HDL2 DL Eco Plus a market leader in tread depth, but the tire was verified by the SmartWay Transport Partnership under strict qualifications for low rolling resistance, according to Roger Stansbie, director of radial truck tire technology development for Continental–the Americas.
“Previously, tires could be submitted for SmartWay verification either as individual tires, or as a combined package of steer, drive and trailer axle tires with a collective rolling resistance (RR) index for all three positions,” Stansbie said. “This latter combination procedure potentially meant that some tires with higher RR indexes than the limit for SmartWay could be verified, because the lower RR index of the partner tires in the combination could make up the difference.
“However, it is generally understood that during 2010, SmartWay will no longer allow this combined method to be used to gain approval. In addition, those tires previously approved using the combined method will have to be re-verified as individual tires before the end of the year.”
The HDL2 DL Eco Plus meets the current standard for the drive axle, and all Continental truck tires currently verified by SmartWay are capable of qualifying on the individual basis, Stansbie said, adding that fleets will not notice any change in our SmartWay lineup when the EPA changes this requirements for qualification later this year.
By anticipating this change to the guidelines and making sure that its products meet the individual requirements, Continental is making sure that trucking fleets that select its SmartWay verified tires will be able to continue using these products for the long haul.
“Trucking fleets can count on Continental to meet and even exceed EPA SmartWay standards for low rolling resistance and fuel economy, now and in the future, to help them lower their overall driving costs,” Armstrong said.
In addition to the HDL2 DL Eco Plus, Continental’s HSL2 (steer), HDL Eco Plus (drive), HTL Eco Plus (trailer) and HTL1 (trailer) are included on the SmartWay list of verified tires.
Tires verified by the EPA for lower rolling resistance can provide a reduction in NOx emissions and an estimated fuel savings of 3 percent or greater, relative to the "best selling" new tires for line haul trucks, when used on all five axles on long-haul Class 8 trucks.
