      Fuel Efficiency Meets High Mileage: Conti EcoRegional Generation 3+ with Reduced Rolling Resistance

      • Update to Conti EcoRegional range: innovative tread compounds and special production processes
      • With 3PMSF symbol indicating suitability for year-round use in all weather conditions
      • Conti EcoRegional HS3+ and Conti EcoRegional HD3+: excellent fuel efficiency helps to protect climate

      Hanover, Germany, March 8, 2022. The Conti EcoRegional Generation 3+ tire line is ideally suited to mixed regional and long-distance haulage. It has been developed for journeys involving multiple deliveries over the course of a day, driving in heavy traffic and winding roads. The tires’ standout characteristics include reduced rolling resistance and superior fuel efficiency, their low CO2 emissions contributing to sustainable mobility and future-proof logistics. “The Conti EcoRegional HS3+ for the steering axle and Conti EcoRegional HD3+ for the drive axle represent an uncompromising upgrade for this tire family,” comments Hinnerk Kaiser, Head of Product Development Bus and Truck Tires at Continental.

      Low rolling resistance, optimum traction, long lifetime

      The new Conti EcoRegional HS3+ retains the innovative tread design of its tried-and-tested predecessor. The new-generation tire once again features pocket sipes to minimize uneven wear and improve water dispersion for optimized performance in the wet. Full-depth sipes continue across 50 percent of the rib width. Specially designed groove geometries ensure uniform transfer of power together with a long tire service life. A large part of the reduction in rolling resistance is down to a modified, innovative compound for the tread.

      Like the Conti EcoRegional HS3+, the new Conti EcoRegional HD3+ cannot be distinguished externally from the model it replaces. The proven low-void design with a high number of gripping edges in the tread delivers low deformation, low rolling resistance and high mileage. Special 3D sipes reinforce tread stability and durability. A substantial reduction in rolling resistance was achieved through the implementation of an enhanced production process for the drive axle. A modified casing construction improves rolling resistance without any negative impact on mileage.

      Enhanced production process: Conti Diamond Technique

      “The tires in the Conti EcoRegional Generation 3+ line are the result of an enhanced production process that lowers rolling resistance without sacrificing mileage performance,” explains Hinnerk Kaiser. “This process involves curing the tires at a relatively low temperature for longer and is known as the Conti Diamond Technique. It has the benefit of giving the polymers and carbon particles more time to react with one another and crosslink effectively, resulting in less internal friction within the compound. This in turn has the effect of improving rolling resistance.”

      Further pluses: year-round usability

      Both the Conti EcoRegional HS3+ and the Conti EcoRegional HD3+ bear the 3PMSF marking on their sidewalls, indicating their suitability for wintry conditions. This means these tires are designed for year-round use in all weathers, including on winter roads and in adverse weather conditions. Certain tire sizes can be ordered with “intelligent” properties; i.e. they leave the factory already equipped with sensors.

      The tires are available in the following dimensions:
