Pneumatic tire without inner tube and unsupported by sidewall

Abstract

Disclosed is a pneumatic tire without inner tube and unsupported by sidewall, wherein a wear-resistant layer or a wear-resistant lubrication layer is disposed at an inner surface rubber layer of a tire outer side, or disposed at an inner surface rubber layer of the tire outer side and a tire inner side. The wear-resistant layer is located at at least one of the following three portions: a tire bead, a tire sidewall, and a tire shoulder. After the tire, which is zero-pressure tire, goes flat, two surfaces of the inner surface rubber layer come into contact with each other, wherein the wear-resistant layer provided at the contact position can improve wear resistance and increase tire mileage and speed limitations.
