RUN-FLAT PNEUMATIC TIRE ASSEMBLY AND METHOD

摘要

A run-flat pneumatic tire assembly includes a pneumatic tire having an elastomeric casing and a tire cavity formed therein. A longitudinally-extending and approximately planar length of strip material is helically arranged within the tire cavity to pre-stress the length of strip material for usage of the pneumatic tire during under-inflated and non-inflated conditions. A method of making a run-flat pneumatic tire assembly is also included.
