Abstract
A wheel structure for use in an engine-powered vehicle having an inner rim, an outer rim, an inner, partially truncated, cone-shaped element, a hub and a closing portion. The outer rim is sealingly attached to the inner rim, while the inner cone-shaped element is oriented with an opening at its truncated vertex end closer to the inner rim than its base and is then attached around the perimeter of its base to the perimeter of the outer rim. A closing portion with an opening at its center is provided which is attached at its perimeter to the perimeter of the inner cone-shaped element. The hub is connected on one side to the truncated vertex end of the inner cone and on the other side to the opening at the center of the closing portion.
