## Abstract

A method and/or article is used for repairing of a worn, damaged, punctured or sliced but otherwise functional vehicle tire, for example on the sidewall of the tire. An external patch includes a layer of adhesive applied directly to the slice or puncture and a patch portion that is applied to an exterior surface of a vehicle tire. A separate adhesive affixes the patch portion to the exterior surface of the tire. The adhesive is in contact with a contact surface of the patch portion and also with the exterior surface of the tire. The adhesive may not form a continuous layer, but may hold the patch to the tire by discrete anchor points of adhesive, the anchor points being separated by adhesiveless areas.

## Claims

### Claim 1

A method of repairing a tire comprises:
applying drops of adhesive around a damaged area of the tire on an external surface of the tire, or on a patch;
after the applying, placing the patch on the damaged area, with the drops of adhesive between the patch and the damaged area; and
after the placing, applying pressure to the patch for at least a predetermined amount of time;
wherein the applying the drops includes applying discrete drops of the adhesive with adhesiveless area left between adjacent discrete drops.

### Claim 2 (depends on 1)

The method of claim 1, wherein the applying the drops includes applying from 0.0444 to 0.133 grams of the adhesive per square inch.

### Claim 3 (depends on 1)

The method of claim 1, wherein the applying the drops includes applying the drops such that 15-40 drops are used per a 1.5 inch×1.5 inch area (6-18 drops per square inch).

### Claim 4 (depends on 1)

The method of claim 1, wherein the applying the drops includes applying the drops such that 40-60 drops are used per a 1.5 inch×1.5 inch area (18-27 drops per square inch).

### Claim 5

A method of repairing a tire comprises:
applying drops of adhesive around a damaged area of the tire on an external surface of the tire, or on a patch;
after the applying, placing the patch on the damaged area, with the drops of adhesive between the patch and the damaged area; and
after the placing, applying pressure to the patch for at least a predetermined amount of time;
wherein the applying the drops includes applying the drops in a grid pattern.

### Claim 6 (depends on 1)

The method of claim 1, wherein the patch is a flexible patch.

### Claim 7 (depends on 1)

The method of claim 1, wherein the patch is a rubber material patch.

### Claim 8 (depends on 7)

The method of claim 7, wherein the rubber material patch has a thickness of 1/16 inch to ¼ inch.

### Claim 9 (depends on 7)

The method of claim 7, wherein the rubber material patch includes polyisoprene.

### Claim 10 (depends on 1)

The method of claim 1, wherein the placing and the applying pressure includes forming an adhesive layer between the tire and the patch, from the drops of the adhesive.

### Claim 11 (depends on 10)

The method of claim 10, wherein the placing and the applying pressure includes dissolving and merging the adhesive layer with rubber of the external surface to form an absorption layer.

### Claim 12

A method of repairing a tire comprises:
applying drops of adhesive around a damaged area of the tire on an external surface of the tire, or on a patch;
after the applying, placing the patch on the damaged area, with the drops of adhesive between the patch and the damaged area; and
after the placing, applying pressure to the patch for at least a predetermined amount of time,
wherein the forming the adhesive layer includes forming a series of discrete anchor points between the patch and the tire, with the anchor points corresponding to respective of the drops, and with adhesiveless space between adjacent discrete anchor points.

### Claim 13 (depends on 1)

The method of claim 1, further comprising, before the applying the drops of the adhesive, cleaning the damaged area.

### Claim 14 (depends on 1)

The method of claim 1, further comprising, before the applying the drops of the adhesive, sanding the damaged area.

### Claim 15 (depends on 1)

The method of claim 1, further comprising, before the placing the patch, applying additional adhesive in the damaged area.

### Claim 16 (depends on 1)

The method of claim 1, wherein the damaged area is a sidewall area of the tire.

### Claim 17 (depends on 1)

The method of claim 1, wherein the damaged area is a treaded area of the tire.

### Claim 18 (depends on 1)

The method of claim 1, wherein the applying the adhesive includes applying a cyanoacrylate compound.

### Claim 19 (depends on 5)

The method of claim 5, wherein the applying the adhesive includes applying a cyanoacrylate compound.

### Claim 20 (depends on 12)

The method of claim 12, wherein the applying the adhesive includes applying a cyanoacrylate compound.
