What Happened
Continental is introducing the new Conti Eco HT 5 trailer tire, completing its fifth-generation Conti Eco portfolio for freight transport. Together with the Conti Eco HS 5 steer tire and Conti Eco HD 5 drive tire, it gives fleets a coordinated solution that combines lower operating costs, high mileage and reduced rolling resistance that can help improve fuel efficiency. Developed for regional and long-distance transport operations, the Conti Eco HT 5 extends the benefits of the Conti Eco Generation 5 family to the trailer axle. While trailer tires are not driven, they account for a significant share of the rolling resistance of a truck and trailer combination, so lowering that resistance at the trailer axle can help cut fuel consumption and, consequently, vehicle-related CO2 emissions during operation.
Up to 50 percent
Depending on vehicle configuration, trailer tires can account for up to 50 percent of the total rolling resistance of a truck and trailer combination, based on a fully loaded 2-axle tractor and 3-axle trailer.
“Every tire contributes to the efficiency and operating costs of a truck and trailer combination. While attention often focuses on the steer and drive axles, trailer tires also play an important role in rolling resistance and fuel consumption. With the Conti Eco HT 5, we are extending the benefits of our fifth-generation Conti Eco portfolio to the trailer axle and helping fleets improve the efficiency of their transport operations.”
- Rolling-resistance-optimized materials, a newly designed sidewall and advanced filler compounds to improve fuel efficiency.
- An innovative tread compound and a refined curing process that contribute to high mileage and long service life.
- A redesigned five-rib tread pattern that promotes even wear, stable handling and consistent performance in varying weather and road conditions on regional and long-haul routes.
- A design aimed at balancing low rolling resistance with high mileage and reliable grip across a wide range of operating conditions.
- Reference product
- Up to 12 percent lower under specified test conditions
- Test methodology, reference product and test conditions available on request
“For the Conti Eco HT 5, our focus was on improving efficiency while maintaining durability. The combination of low rolling resistance, long service life and balanced wear characteristics can help fleets reduce tire-related operating costs while maintaining reliable performance in demanding transport operations.”
The Conti Eco Generation 5 portfolio forms part of Continental's broader effort to support customers in improving transport efficiency through technological innovation and optimized tire performance. By combining low rolling resistance, high mileage and long service life across all axle positions, the portfolio addresses key industry challenges including rising fuel costs and increasing regulatory and customer requirements related to transport efficiency and emissions reduction. The Conti Eco HT 5 will be available starting September 2026 in two sizes: 385/65 R 22.5 and 385/55 R 22.5.
Previously from Continental
Continental has been broadening its commercial vehicle tire line-up alongside this launch. In mid-September 2026, the company added a 315/60 R 22.5 steering axle tire to its Conti Scandinavia winter tire portfolio for commercial vehicles. That addition, like the Conti Eco HT 5, filled a specific axle position in a truck's tire setup.

Why this matters
Trailer tires are easy to overlook, yet they can account for up to half the rolling resistance of a loaded truck and trailer combination, so they feed straight into fuel bills and vehicle-related CO2 emissions. That makes this launch relevant to fleet operators in regional and long-distance freight, who face rising fuel costs and growing regulatory and customer demands on efficiency and emissions. Continental now offers a coordinated tire package covering the steer, drive and trailer axles.
Terms in This Story
- rolling resistance
- The drag a tire creates as it flexes while rolling, which works against the vehicle and adds to the energy needed to keep it moving.
- trailer axle
- The axle under a trailer, which carries load but is not powered; its tires roll freely and are pulled along by the tractor.
- drive axle
- The axle whose wheels receive power from the engine and push the vehicle forward, as opposed to an unpowered, rolling axle.
- curing process
- The heating step in tire manufacturing in which the rubber compound is shaped and strengthened inside a mold.
