Abstract

A pneumatic tire comprises various tire components each comprised of a rubber-coated layer containing a given number of reinforcing elements. In at least one of these rubber-coated layers, not less than 30% of all reinforcing elements are divided into plural groups each comprised of a combination of m-steps and n-rows viewing in a thickness direction of the rubber-coated layer, in which each of m and n is an integer of 2 or more representing the number of the reinforcing elements, and a distance between mutually adjacent and opposite reinforcing elements not grouped with each other is wider than a distance between mutually adjacent reinforcing elements in the group.
