      Continental Manufactures First Tire with New “HL” Load Index Code

      • Higher load capacity for heavy electric or hybrid passenger cars and SUVs
      • Load capacity almost one quarter higher than standard tires

      Hannover, January 21, 2021. Large, powerful cars and SUVs with electric or hybrid drive put far more weight onto the road than conventional vehicles. At the same time, these heavier models offer little scope for fitting larger tires with higher load capacities. In response, Continental is now manufacturing the first passenger tire with the new “HL” load index code. Inflated to the same pressure, these tires have a higher load capacity than those built to the former XL standard. On the sidewall, products with the new maximum load capacity display the HL code ahead of the size, as in “HL 245/40 R 19 101 Y XL”. The load capacity of this HL tire stands at 825 kg (load index 101), which equates to a 10 percent increase over the familiar XL standard of 750 kg (load index 98). Passenger tires of this size built to the SL standard, adequate for many cars, up to and including mid-range models, can take a maximum load of 670 kg (load index 94). That makes the load capacity of the new HL tires almost one quarter higher. Looking ahead, Continental is expecting to see growing demand from OEMs for tires with the new HL code.

      Increasing the load capacity while at the same time meeting customer requirements called for a number of changes in both the tire structure and the rubber compound. “We were dealing here with tradeoffs that needed resolving at a very high level,” explains Dr. Stefan Habicht who was in charge of the development project for these tires. “In terms of construction, we reinforced the bead and enhanced the contour of the tire to reduce tire/road noise. At the same time we also optimized the pattern compound. As a result, we were able to achieve low rolling resistance, ensure precision handling and keep mileage at its customary high level.”

      Continental is currently producing the first tires to the new HL standard for OE fitments, but they will also be available on the replacement market.
