Abstract

Methods of repairing tire portions have steps that include removing at least part of the damaged portion of the tire to form an aperture or opening through the tire; forming one or more grooves in the tire adjacent to and extending from the aperture; placing at least one repair reinforcement within each of the one or more grooves; placing a patch on the tire to cover the aperture and each repair reinforcement; and, applying material to fill the remainder of the opening.

Claims

1. A method of repairing a damaged portion of a tire, the method comprising the steps of:

removing at least part of the damaged portion of the tire to form an opening through the tire;

forming a plurality of grooves along an exposed surface of the tire adjacent to and extending from each of a pair of opposing radial ends of the opening, each of the plurality of grooves having a length extending away from the opening and the plurality of grooves being spaced apart in a side-by-side arrangement along a perimeter of the opening at each of the pair of opposing radial ends of the opening;

placing at least one repair reinforcement within each of the plurality of grooves, each of the repair reinforcements extending across the opening where opposing ends of each reinforcement are arranged in one of the plurality of grooves on each of the pair of opposing radial ends of the opening;

placing a patch on the tire to cover a first side of the opening and each at least one repair reinforcement, the patch being separate from each at least one repair reinforcement and the step of placing at least one repair reinforcement occurring before the step of placing a patch on the tire; and

,

applying material to fill the remainder of the opening.

2. The method of claim 1, wherein the exposed surface in which the plurality of grooves are formed is an inner surface of the tire, and the patch is placed on the inner surface of the tire.

3. The method of claim 1, wherein the material is applied to fill the remainder of the opening on a side of the tire opposite the repair reinforcements and the patch.

4. The method of claim 1, wherein the length of each of the plurality of grooves extends substantially parallel to at least one adjacent tire reinforcement.

5. The method of claim 1, wherein the length of each of the plurality of grooves extends in a radial direction relative to the tire.

6. The method of claim 1, wherein the length of each of the plurality of grooves extend substantially parallel to one another.

7. The method of claim 1, further comprising the step of curing at least the repaired portion of the tire.

8. The method of claim 1, wherein the at least one repair reinforcement is contained within a repair ply, the repair ply comprising a sheet of rubber, containing the at least one reinforcement.

9. The method of claim 1, wherein prior to positioning the at least one repair reinforcement into the plurality of grooves, the method further includes a step of cutting each of the one or more repair reinforcements to a length to fit within each of the plurality of grooves.

10. The method of claim 1, wherein before the step of placing the at least one repair reinforcement within each of the plurality of grooves, rubber cement is first placed into each of the plurality of grooves.

11. The method of claim 1, wherein the patch comprises a plurality of reinforcements embedded therein.

12. The method of claim 1, wherein an end of the length of at least two of the plurality of grooves arranged away from the opening are offset relative to each other in a longitudinal direction of the at least two grooves.

13. A repaired tire having:

a repaired damaged portion having a filled opening extending between an outer and inner surface of the tire, the filled opening including cured material extending between the outer surface of the tire and one or more repair reinforcements extending across the filled opening where opposing ends of each reinforcement are arranged in one of a plurality of filled grooves arranged adjacent to and extending from each of a pair of opposing radial ends of the filled opening, each of the plurality of filled grooves having a length extending away from the filled opening, the plurality of filled grooves being spaced apart in a side-by-side arrangement along a portion of a perimeter of the opening at each of the opposing radial ends of the opening;

a patch arranged along a surface of the tire to cover the filled opening and the one or more repair reinforcements.

14. The repaired tire of claim 13, wherein each of the one or more grooves has a length extending substantially parallel to at least one adjacent tire reinforcement extending within the tire.

15. The repaired tire of claim 13, wherein the patch comprises a plurality of reinforcements embedded therein.

16. The repaired tire of claim 13, wherein an end of the length of at least two of the plurality of filled grooves arranged away from the opening are offset relative to each other in a longitudinal direction of the at least two grooves.
