A tire includes a circumferential tread, a pair of beads, and a pair of sidewalls. The tire further includes a plurality of circumferential belts disposed below the circumferential tread and extending in an axial direction. The plurality of circumferential belts include a lower belt and an upper belt. The tire also includes at least one gum strip. The at least one gum strip has a first portion in contact with a top surface of the lower belt and a bottom surface of the upper belt. The at least one gum strip has a second portion disposed below the lower belt.

A tire having a crown reinforcement formed of at least two working crown layers having unequal axial widths, a layer C of rubber mixture being positioned between at least the ends of the said at least two working crown layers, and the crown reinforcement having at least one layer of circumferential reinforcing elements positioned radially between two working crown layers. The distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by the layer C of rubber mixture is such that 1.1<d<2.2, being the diameter of the reinforcing elements of the said at least one layer of circumferential reinforcing elements, and, in a meridian plane, the thickness of the layer C of rubber mixture is substantially uniform.

In a pneumatic tire, both of a thickness of the first belt layer and a thickness of the second belt layer in the tire center portion are 1.00 mm or less, and when the shortest distance between the cord of the second belt layer and the cord of the first belt layer in the tire center portion is defined as a, and the shortest distance between a cord closest to an end of the second belt layer and a cord of the first belt layer is defined as b, b/a is 1.8 to 4.0, and at an end of the belt, an end rubber is disposed in a predetermined manner on a tire radially inner side of the first belt layer, between the first belt layer and the second belt layer, and on a tire radially outer side the second belt layer.
