## Abstract

A device to enhance tire traction comprises a two sided strip, one side of which is adhesive to the surface of a tire and the other side of which has affixed pebbles or similar discrete hard objects such as gravel, providing a traction surface for the tire. The discrete objects are roughly 5 to 12 millimeters along major axes and are as thin as 2 to 3 millimeters. The discrete objects are affixed to the strip with a spacing between adjacent objects averaging 5 to 10 millimeters, thereby providing interstices between the objects.

## Claims

### Claim 1

A device to enhance vehicle tire traction, the device comprising:
a flexible strip having two surfaces, on the first surface of which is deposited an adhesive material compounded to adhere the strip to the surface of a tire, and on the second surface of which are deposited hard objects affixed to the strip, the objects so distributed that the mean distance between two adjacent such objects is about 5 to 10 millimeters.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the hard objects are 5 to 12 millimeters in width, 5 to 12 millimeters in length, and more than 2 millimeters in thickness.

### Claim 3 (depends on 2)

A device according to claim 2, wherein the hard objects are pieces of gravel.

### Claim 4 (depends on 2)

A device according to claim 2, wherein the hard objects are pieces of lava rock.

### Claim 5 (depends on 2)

A device according to claim 2, wherein the strip is about 10 to 15 centimeters in width.

### Claim 6 (depends on 2)

A device according to claim 2, wherein the strip is about 15 to 40 centimeters in length.

### Claim 7

A device to enhance vehicle tire traction, comprising:
A plasticized rubber sheet having two surfaces, on the first surface of which is deposited layer of adhesive, the adhesive comprising a mixture of hydrogenated rosin glycerol ester and maleated rosin glycerol ester, and on the second surface of which are affixed pieces of rock, such pieces 5 to 12 millimeters in width, 5 to 12 millimeters in length and at least 2 millimeters in thickness, the pieces of rock affixed to the second surface of the sheet with polyurethane glue and disposed on the sheet to leave an average of 5 to 10 millimeters between adjacent pieces of rock.
