riginally included as part of the U.S.
Environmental Protection Agency (EPA) and
National Highway Traffic Safety Administration
(NHTSA) Phase 2 greenhouse gas (GHG) emissions
standards regulations, trailers were considered an
additional step toward fuel efficiency improvements.
While federal regulations regarding trailers have been
put on hold for the indefinite future, trailer manufacturers are still taking steps to improve the efficiency
of their products.
"Should the regulations become effective in the
future, trailers will have to be compliant with the
EPA GHG [Phase] 2 rules, which mandate incremental
stringency increases by phase years 2021, 2024, and
2027," says Chris Lee, vice president of engineering
for trailer manufacturer, Great Dane.
Even without mandates dictated by the Phase 2
ruling, trailer manufacturers have been exploring and
offering efficiency improvement technologies outlined
in the originally proposed regulations such as lighter weight materials for trailer construction, aerodynamic side and rear fairings, low rolling resistance
(LRR) tire specifications, and tire monitoring systems
including tire pressure monitoring systems (TPMS)

efficiency-improvement technologies such as
lighter weight materials, aerodynamic devices,
low rolling resistance tires, and tire monitoring
systems including tire pressure monitoring
systems or automatic tire inflation systems.

or automatic tire inflation systems (ATIS).
"There is definitely value to running LRR tires on
the trailer," advises Phil Mosier, manager of commercial tire development at Cooper Tire. "The trailer positions can account for up to 42 percent of the total
vehicle's rolling resistance coming from the tires."
"Many fleets are already running with side skirts
and low rolling resistance tires and experiencing
the benefits in improved fuel efficiency," says Larry
Adkins, senior manager for trailer manufacturer
Wabash National. "This is a trend that the industry
has been moving toward as fleets determined, on their
own, what technologies made the most sense for their
operations. As the regulation's requirements step up
over the years, we will see the cost of a new trailer
increase as more advanced technologies will need
to be installed."
