Method For Mounting And Inflating Tubeless Tires

View page
US Patent:
40195538, Apr 26, 1977
Filed:
Dec 24, 1975
Appl. No.:
5/644099
Inventors:
James I. Lefgren - Smithfield UT
International Classification:
B60C 2500
US Classification:
157 11
Abstract:
A tubeless tire to be mounted is placed on a wheel rim so that a side-wall bead of the tire is in contact with the adjacent wheel rim flange. A plastic, water soluble substance of doughy consistency is then placed in the gap between the opposite side-wall bead and its adjacent wheel rim flange to form an airtight seal. Air is then introduced into the tire in the conventional manner through the wheel rim valve until desired inflation is achieved. During inflation, the plastic substance is expelled and may be manually removed and/or washed off with water. In the case of large tires, wherein the gap between the side-wall bead and its adjacent wheel rim flange is large, the quantity of the plastic substance used is minimized by first inserting a flexible annulus, such as an inflated tube, into the gap.
