Aggressive tread pattern with massive sized blocks protects the shoulder area reducing the risk of damage. Increased tread depth for longer life. Excellent resistance to abrasion and cuts thanks to more durable special rubber compound as well as to the reinforced metal layers under the tread. A special rim cushion with metal cord strengthens the bead zone and increases reliability in difficult conditions. Technology of coiling the bead ring from separate wires - Winding ring bead - reduces tension in bead zone and makes wheel balancing and rim fitting easier. A reliable bead ring with good rim fitting provides airtightness.
