Continental has announced the Conti Eco HT 5 trailer tire, which completes the company’s fifth-generation Conti Eco portfolio for freight transportation. It joins the Conti Eco HS 5 steer tire and Conti Eco HD 5 drive tire as part of a coordinated tire range designed to reduce rolling resistance, operating costs and fuel consumption.
Developed for regional and long-distance transportation, the Conti Eco HT 5 extends the Conti Eco Generation 5 range to the trailer axle. Although trailer tires are not driven, they contribute to the rolling resistance of a truck and trailer combination. Reducing rolling resistance at the trailer axle can therefore help lower fuel consumption and vehicle-related CO2 emissions during operation.
“Every tire contributes to the efficiency and operating costs of a truck and trailer combination,” explained Hinnerk Kaiser, who is responsible for the development of truck and bus tires in the EMEA region at Continental. “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.”
Trailer efficiency
A trailer typically runs on multiple tires that are continuously in contact with the road. As a result, trailer tires have a direct impact on stability, fuel efficiency and overall operating performance. Depending on vehicle configuration, trailer tires can account for up to 50% of the total rolling resistance of a truck and trailer combination.
The Conti Eco HT 5 has been engineered to deliver a good balance of low rolling resistance and high mileage, while promoting even wear and providing reliable grip across a wide range of operating conditions. The tire incorporates rolling-resistance-optimized materials, a newly designed sidewall and advanced filler compounds to improve fuel efficiency.
High mileage and long service life
According to Conti, an innovative tread compound and refined curing process contribute to high mileage and long service life, and a redesigned five-rib tread pattern promotes even wear, stable handling and consistent performance in varying weather and road conditions on regional and long-haul routes. Compared with the Conti Hybrid HT3+, the new Conti Eco HT 5 reportedly delivers up to a 12% reduction in rolling resistance under specified test conditions. These improvements can help fleets reduce fuel consumption and CO2 emissions and decrease tire-related operating costs.
“For the Conti Eco HT 5, our focus was on improving efficiency while maintaining durability,” explained Kaiser. “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.”
By combining low rolling resistance, high mileage and long service life across all axle positions, the portfolio helps customers address key industry challenges, including rising fuel costs, increasing regulatory and customer requirements related to transportation efficiency and emissions reduction.
The Conti Eco HT 5 will be available starting September 2026 in the following sizes: 385/65 R 22.5 and 385/55 R 22.5.
