Run flat tire insert system

Abstract

A tire insert system for assembly into a continuous ring during its positioning within a tire, and is supported on a wheel web between the wheel flanges where the continuous tire insert ring is mounted to the wheel to support a tire load for a significant travel distance should that tire lose air. The tire insert segments each include an arcuate shaped outer portion that, when assembled end to end with other tire insert segments, form the insert ring, and each tire insert segment includes an anchor plate that is an arcuate section when assembled side by side with other anchor plates forms a flat disk having an open center portion, which anchor plate is secured to the tire insert on its top end and includes mounting holes formed in its lower portion for receiving bolt type fasteners fitted therethrough and through forward and rear wheel sections, sandwiching the anchor plates therebetween, forming the tire insert ring in the tire during a mounting of the tire between wheel flanges.

Description

BACKGROUND OF INVENTION [0001] 1. Field of The Invention [0002] This invention pertains to a run flat tire insert system for a transport tire. [0003] 2. Prior Art [0004] The present invention is in a tire insert system for fitting into a tire, such as an automobile or truck tire. The insert is formed into a ring, preferably from four sections, that are fitted together into a ring within a tire during the process of mounting the tire on a wheel. Which wheel is formed from front and rear sections, with the rear section preferably including a wheel web and a flange and includes a foot section that is for coupling to the wheel front section, forming the wheel that will hold and maintain a tire containing the ring insert at the tire beads. The tire insert is assembled from tire insert segments that are each fitted into the tire during the mounting of the tire on the wheel, with the insert segments each for mounting, at aligned holes in the front and rear wheels, with the same nut and bol...

AI Technical Summary

Benefits of technology

"The present invention is a tire insert system for mounting to a wheel, which includes individual arcuate shaped outer bars formed from an elastomeric material. The tire insert system can be easily mounted and dismounted from a worn tire, and can be easily fitted into a new tire. The tire insert system provides a minimum tire side wall flexure should air be lost from the tire during operation, allowing a vehicle to travel a significant distance and speed after the tire has gone flat. The tire insert system is formed in a plurality of sections that are fitted together into a ring shape, with each tire insert fixed onto a disk mounting plate that is at approximately a right angle to the tire insert undersurface and is for mounting to a wheel."

Problems solved by technology

Such flat tire, when operated at only fifty miles an hour or less, will, because of the deep side wall folds, experience flexure in its side wall as it rolls under load that rapidly and heat the tire to, in short order, cause the tire to overheat and begin to fall apart.
