Segmented-band banded tire

摘要

A banded radial run-flat pneumatic tire with a transversely segmented band that varies the bending stiffness of the band circumferentially relative to the bending stiffness across the band. The band can be segmented into annular side-by-side hoop-like coaxial band elements either of the same or of different diameters. An elastomer bonded between adjoining circumferential edges of the band elements connects them for cooperative association to give the band its desired operating characteristics. The elasticity of the elastomer and the spacing between the band elements can be selected to tailor the performance of the band. Preferably the bending stiffness of the band is 1000 times as great circumferentially as it is transversely across the band.
