Abstract: In a pneumatic tire, a difference Gs-Ge falls in a range of Gs-Ge≧0.10, where Gs is a groove area ratio for a wear rate 0% and Ge is a groove area ratio for a wear rate 100%. Further, a groove area ratio G for a wear rate 20% falls in a range of (Gs-G)/(Gs-Ge)≧0.30, and a groove area ratio G for a wear rate 35% falls in a range of (Gs-G)/(Gs-Ge)≧0.50.

Abstract: A pneumatic tire comprises a carcass layer, a belt layer disposed on an outer side of the carcass layer in a tire radial direction, and a tread rubber disposed on the outer side of the belt layer in the tire radial direction. The belt layer is formed by laminating a pair of cross belts having a belt angle of not less than 10° and not more than 45° in absolute values and having belt angles of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to the tire circumferential direction. A tread width TW and a total tire width SW have a relationship such that 0.79≦TW/SW≦0.89.

Abstract: A pneumatic radial tire includes: at least one carcass layer suspended across left and right bead parts; a belt layer arranged on an outer circumferential side of the carcass layer; and a tread arranged on an outer circumferential side of the belt layer. The tread has a laminated structure in which a thermoplastic film layer of a thermoplastic resin or a thermoplastic elastomer composition is interposed between a tread-side rubber layer and a belt layer-side rubber layer. The thermoplastic elastomer composition is obtained by blending an elastomer in a thermoplastic resin. A process for producing a retreaded tire includes the steps of: forming a base tire from the pneumatic radial tire by softening the thermoplastic film layer through heating so as to separate and remove the tread-side rubber layer, the pneumatic radial tire having the tread worn away; and subsequently bonding a new tread-side rubber layer onto the base tire.
