Continental Tire the Americas says its HSC1 (heavy steer construction) is a steer tire with tread pattern and compound chosen for optimal original mileage with "excellent" self-cleaning properties in a three-groove design.
 
A wider tread and shoulder ribs are said to improve wear and increase performance, while the patented tread pattern and contour provide reduced stone retention and improved impact resistance. The HSC1 is available in sizes 11R22.5 and 11R24.5 for load range H, with 12R sizes too.
 
There’s also an extra-deep drive tire for construction service, the recently launched Continental HDC1 (heavy drive construction) with a full 32/32 in. tread depth and a new self-cleaning tread pattern. A heavy-duty compound and aggressive open-shoulder design were chosen to provide superior original mileage and traction, the company says, while the tire’s optimized contour ensures higher load capabilities with less deformation.
 
The HDC1 also features technologies to reduce stone retention, said to result in fewer casing penetrations. The available sizes are also 11R22.5 and 11R24.5 in load range H.

Both tires, designed and produced at the company’s Mt. Vernon, Ill. research center and truck tire plant, use Continental’s new on/off-road compounding, which is said to increase resistance to tread cuts, chips and chunks and reduce the depth of tread damage. Continental’s exclusive “Stable” bead construction was included in both new products for better structural durability and extended product life. Likewise, Continental claims that a premium four-ply belt with reinforced second and third belt for both new tires prevents fatigue fractures and withstands highly concentrated pressure.
