Abstract
Abstract A lightweight, filler core tire construction for automobiles and other vehicles, having a flexible composite outer layer structure and a flexible honeycomb core bonded to said outer layer, eliminating pressurized air from the tire and increasing thus the safety of driving and the damage resistance and eliminating the servicing of the tire. The structures above are preferably made from a polyurethane polymer and various fibers.
