Abstract: PURPOSE:To effectively prevent adherence of mud and to manufacture a mud adherence preventive tire having no difficulty in durability by coating an outer surface of the tire which is vulcanized and molded with inactive polymer and then fixing it to the outer surface of the tire by heat treating. CONSTITUTION:A green tire shaped with crude rubber and cord material is vulcanized and molded in a mold. An outer surface of a tire 1 for a vehicle which is finished to be vulcanized and molded is coated with inactive polymer, the polymer is then fixed to the outer surface of the tire 1 by heat treating to form a seized coating 2. Thus, the tire 1 has the high water repellent coating 2 on the entire surface of a skid base area Sh and a sidewall S of a case body. Adherence of mud to the parts is effectively suppressed, and a fear of bringing mud is alleviated even at the time of escaping from a field.

Abstract: PURPOSE:To delay ignition and combustion speed as far as possible while keeping dynamic performance such as wear resistant property and the like as a tire and perform self-extinguishing in a short time by forming a rubber layer in a shoulder area including a tread end part of a fire retardant rubber layer having higher fire retardancy than other outside surface parts. CONSTITUTION:At least an outside surface part of a tread rubber layer is formed of a fire retardant rubber layer 1 having an oxygen index within a range of 19.8-27.5. A rubber layer in a shoulder area including a tread end part P is formed of a fire retardant rubber layer 2 whose oxygen index is 25.0 or more and having higher fire retardancy than other outside surface parts. When combustion is caused in the tire tread as in the case where electric leakage in an electric vehicle is grounded from the tire tread surface to cause ignition, ignition and combustion speed is delayed as far as possible while keeping dynamic performance such as wear resistant property and the like as a tire, and self-extinguishing is conducted in a short time.
