SmartWay, the public/private collaboration between the EPA and motor carriers, works to further its goal of reducing fuel consumption in freight transportation operations, lowering harmful emissions in the process, and helping participating fleets reduce costs.
A key part of achieving those objectives is the SmartWay Technology Program, a testing, verification and designation initiative that identifies equipment, technologies and strategies that have the potential to save fuel and reduce greenhouse gases and other air pollutants from freight transport. The program establishes performance criteria and reviews test data on vehicles, equipment and technologies.
Through grants, cooperative agreements, emissions and fuel economy testing, demonstration projects and technical literature review, EPA has evaluated the fuel saving benefits of various vehicles, systems and components. The result is a continually updated list of SmartWay Verified Technologies, including tires and aerodynamic devices.
TIRES & RETREADS
EPA has determined that certain tire models can reduce NOx emissions and fuel use by 3% or more on Class 8 tractors and trailers in linehaul operations. The following tires and retreads are SmartWay verified:
Bridgestone offers a variety of SmartWay-verified tires. Bandag retread products on the list of verified retreads include the B710 FuelTech, the B197 FuelTech and the B135 FuelTech wide base trailer retread. In addition, Bandag expects its FCR Trailer retread to be added to the SmartWay list.
Continental’s ContiEcoPlus HD3, a new long-haul highway drive tire, became SmartWay verified in February 2013. The ContiEcoPlus HD3 offers improved rolling resistance, a premium belt package and other features designed to enhance retreadability.
Double Coin’s OptiGreen Series includes the FR605, FD405, FT105, and two super wide trailer position tires, the FT425 and FT125. Included is a seven-year limited casing warranty on select OptiGreen products.
Eight Goodyear Fuel Max truck tires have received SmartWay verification. Recently, three Goodyear retread tires received SmartWay verification: the G316 AT Fuel Max, G572 LHD Fuel Max and G305 ATS Fuel Max. Three Dunlop tires also are SmartWay Verified Technologies.
Hankook SmartWay approved products include the AL11 and AL07+ steer tires with new casing and tread technologies designed to enhance fuel efficiency. Also offered are the AH24 all-position regional haul, DL11 and Z35A drive tires and the TL01 trailer tire.
Marangoni Tread North America
Marangoni’s splice-less Ringtread SmartWay verified product is the Energeco trailer RTA-E, 12/32-in., 4 rib model with advanced compounding and tread designed to maximize fuel efficiency. Energeco drive RDA-E 25/32-in. and wide base Ringtreads soon will be verified .
Michelin SmartWay verified tires and retreads include XZA3+ Evertread, XZA1+, XZA2 Energy and X Coach XZ steer tires; XDA Energy, XDA3, X One XDN2 , X One XDA Energy, X Multi Energy D and X Line Energy D drive tires; and XTA Energy, XT-1, X One XTA and X One XTE trailer tires. Retreads include XDA2 19 and 23, and X One XDA-HT drive, and XT-1 AT and X One XTA Pre-Mold trailer models.
The SmartWay verified 709ZL drive tire from Yokohama employs the company’s Zenvironment technology, which combines the latest in casing, rubber compounding and tread design. Set to debut in March are the 445/50R22.5 TY517 ultra low profile wide base drive tire and the RY407 wide base trailer tire.

Regulations that took effect in California at the beginning of 2013 have placed added emphasis on the use of trailer aerodynamic devices. As of the beginning of this year, all 2011 and newer 53-ft. or longer dry and refrigerated van trailers that operate on California highways must comply with the Air Resources Board Tractor-Trailer Greenhouse Gas regulation. With certain exceptions, fleets must ensure their trailers are equipped with EPA SmartWay Verified aerodynamic equipment.

ATDynamics offers two SmartWay approved Advanced Trailer End Fairings, the standard TrailerTail and the shorter, three-sided TrailerTail Trident. Both products are compatible with swing door equipped dry van, refrigerated, drop-frame and curtainside trailers.
Air Slipper trailer side skirts from Fleet Engineers now feature a flexible lower extrusion to prevent damage from obstacles. Designed with 16 gauge, ribbed aluminum, the skirts fit most trailers by clamping to crossmembers, eliminating the need to drill holes in the frame. Included are zinc support hardware and stainless steel attachment hardware.
Freight Wing offers SmartWay verified side skirts, which have been SAE/TMC fuel economy tested. The AeroFlex Composite, which is designed to maintain its flat panel shape, joins Freight Wing’s AeroFlex DMP, constructed of heavy-duty Dense Matrix Polyethylene.
Two of the seven SmartWay approved aerodynamic devices for trailers offered by Laydon include the Trailerskirt TS225 center-mounted and TS248 two-sided models. Both products use the company’s patent pending flexible mono strut, which allows the panels to bend inward and outward. The TS225 comes with black or white thermo set panels from Crane Composite and the TS248 has Crane ArmorTuff panels.
Green Wing side skirts from Ridge Corp. feature a heavy-duty hem, which improves impact protection and reduces fairing weight by 15%. The side skirts also are designed with a Ground Clearance Arc, which allows a trailer to travel over obstacles such as railroad tracks and sunken docks without incurring skirt damage.
Transtex trailer skirts include the C160 made of a glass-reinforced thermoset composite material. The Flex Skirt model’s glass-reinforced thermoplastic composite has a glossy finish and a higher puncture rating. The matte finish Maximum Flex Skirt model also features high impact resistance, as well as glass-reinforced cross-weaved thermoplastic panels that provide for maximum inward flexibility.
Alcoa Wheels: Current and future innovations
Alcoa states that it invented the first forged aluminum wheel in 1948, and its position within the market as a key supplier continues to be as a market segment leader. The company’s innovative spirit is one of the reasons why it leads the marketplace. Knowing that overall lifetime operating savings is the primary goal of its customers, Alcoa reminds that it has launched numerous products over the past 10 years to contribute to this savings, including Dura-Bright, LvL ONE, Wheel Torque Solutions and its most recent advancement—new Wide Base wheels.
Alcoa’s 14-in. wide base aluminum wheels are not only the lightest on the market, weighing just 58 lbs. per wheel, but they also offer enhanced image, as well as solutions to achieving sustainability goals. Simply switching single steel 22.5.in wheels and tires to 14.in. wide base Alcoa aluminum wheels and tires reduces the weight of an 18-wheeler by nearly 1,400 lbs. The upgrade takes advantage of this significant weight reduction coupled with the increased savings from lower resistance wide base tires to further improve fuel efficiency. Alcoa wheels’ strength, durability and low weight deliver environmental advantages to complement their financial benefits. With larger payloads due to the weight savings, trips are reduced, and, since Alcoa wheels are infinitely recyclable, they’ll never see a landfill.
Alcoa said it is hard at work at bringing new innovations to further increase fuel efficiency, payload, enhanced appearance and ease of maintenance. New products will soon be on the market. Alcoa’s number one priority is to design, engineer and manufacture unique wheel products, finish options and other advancements that its customers prefer. Alcoa is proud and excited about advancing future innovations and looks forward to continuing to serve its loyal customers and lead the market.
