An asymmetric body ply skim layer using composite materials eliminates the innerliner to cut weight and rolling resistance without exposing reinforcing cords.
An inner liner combines styrene-isobutylene-styrene copolymer with modified isobutylene to lower mass without sacrificing air retention or crack resistance.
A multilayer tire inner liner combines a low-elongation barrier layer with a high-elongation elastomer layer to disperse stress.
A butyl rubber composition uses a low glass transition temperature terpene resin to enhance air permeation resistance and moldability.
A polyamide resin composition incorporates a modifying polymer with reactive functional groups to enhance tensile properties.
A pneumatic tire uses a conductive sheet reaching the rim strip to discharge static electricity.
