The EPA's SmartWay program helps companies reduce transportation-related emissions by measuring, benchmarking, and improving freight transportation efficiency. Launched in 2004, SmartWay® creates incentives to improve supply chain fuel efficiency.
Verified Low-Rolling Resistance (LRR) Tires & Retreads
The EPA has determined that certain low-rolling resistance (LRR) tires and retread technologies can reduce NOx emissions and fuel use by 3% or more, relative to the best-selling new tires for long haul Class 8 tractor-trailers. If a tire is used on a different truck type or axle position, the tire is not considered SmartWay® Verified for that application.
These improvements are achieved under the following conditions:
The following Continental low-rolling resistance (LRR) tiers are SmartWay® Verified when used on Class 8, long haul tractor trailers:
| Steer Tires | Drive Tires | Trailer Tires |
| HSR2 | Conti HDL 3 LTL | Conti EcoPlus HT3 |
| HSR2 SA | HDL2 | Conti HTL 3 |
| Conti HSL 3 | HDL2+ | HTL1 |
| Conti HSR 3 | HDL2 Eco Plus | Conti Hybrid HT3 |
| Conti Coach HA3 | HDL2+ Eco Plus | |
| Conti EcoPlus HS3+ | HDL2 DL Eco Plus | |
| Conti Hybrid HD3 - 19.5" | ||
