Abstract
An inside repair for tubeless tires is provided wherein a measured amount of an air (or moisture) curing elastomeric adhesive is applied to the cleaned and primed inner surface of the tire over the puncture hole, a porous path is placed over the adhesive and the adhesive is then forced into the puncture hole by use of a cup-shaped tool lined with a release material. After the material has cured sufficiently to form a substantial skin, the tire is inflated. Thereafter, the repair cures fully with the tire in the strained condition of inflation. The elastomer is of low durometer and is compatible for adhesion to rubber.
Claims8
A method for making an inside repair of a puncture, including cracks collaterally thereof, on a cleaned and primed inner surface of a tubeless tire comprising the steps of:
- (a) applying an uncured but air-curing elastomeric adhesive to the inner surface of said tire over said puncture and cracks,
- (b) placing a porous patch over said adhesive,
- (c) compressing said patch and uncured adhesive while confining the flow of said adhesive to force adhesive substantially into said puncture and cracks,
- (d) allowing said adhesive at least partially to cure, and
- (e) inflating said tire while a substantial portion of said adhesive is still in the uncured state.
A method of inside repairing a puncture in a tubeless tire, which puncture has not damaged the tire to the point of unsafe driving, which method comprises the steps of:
- (a) applying a self curing adhesive mixture to the inside surface of a puncture,
- (b) forcing the adhesive into the puncture hole,
- (c) allowing the adhesive to cure sufficiently in the hole merely to avoid being blown out by inflation of the tire to a pressure of about 5 psi greater than the designed pressure of said tire when a puncture of a safe nature is being repaired;
- (d) thereafter inflating said tire to about 5 psi greater than its designed pressure, and
- (e) allowing the adhesive to cure fully;
- whereby a visible indication of an oversized or unsafe puncture is provided either by the blowing out of said adhesive or by a tell tale bulge on the surface of said tire.
