The Continental HDC1 Tyre offers durability, high mileage, long service life - three features that now take you even further. All in all, this means increased resistance to the extreme demands made by construction sites, plus enhanced economy of your vehicles. The Continental HDC1 Tyre has an advanced tread pattern developed for further improved traction. Tread area :Means increased resistance to cuts, chipping and chunking, Reduces the number, and most importantly the depth of any cuts and tears, Improves protection of the casing by keeping damage superficial, Results in substantially higher removal mileage, thanks to its great durability. Belt layer: Withstands highly concentrated pressure, Prevents fatigue fractures, Means enhanced traction characteristics through the stiffness of the overall structure, Protects the casing effectively and offers best retreadability. Tread pattern: Results in considerably higher mileage with even wear, Ensures reliable grip and good handling both on and off the road, Improves the tyre's self-cleaning characteristics and reduce stone-trapping (casing protection), Combines high mileage with significant traction and optimum road suitability, whatever the weather conditions. Contour: Provides greater resistance to deformation caused by radial forces, Minimizes compression of the sidewalls, even with heavier loads, Counteracts premature material fatigue, Means greater load-carrying capacity and improved retreadability.
