The DPT306 is a premium regional drive tire with sidewall protection ribs designed for all weather conditions. The addition of sidewall protector ribs, to help withstand abrasion and cuts caused by curb damage, improves the durability of the tire. This added feature will help to increase tire life and the ability to retread the worn casing to lower your overall tire cost. The closed shoulder design provides a stable ride for excellent vehicle handling and control, while the center lugs provide any needed traction.
