## Abstract

A self-sealing pneumatic tire having at least one cohesive sandwich radially inward of the pneumatic tire is provided. The at least cohesive sandwich may include a cohesive material under pressure, facilitating a recovery capacity upon being pierced by a sharp object, whereby the molecules of the cohesive material cohesively reattach, self-sealing any passageway or space created by the sharp object. The self-sealing pneumatic tire may also provide a loculated-diamond-section layer located radially inward of the outer cohesive sandwich, further supporting the self-sealing pneumatic tire. The external rubber tread are disposed along the circumference of the tire in some embodiments can be separate from the surface of the tire yet secured in place by attachments. Once fully utilized, this external rubber tread can be replaced by a new version without having to replace the entire tire.

## Claims

### Claim 1

A device, comprising:
a pneumatic tire having an outer circumference and an inner pneumatic chamber;
a first cohesive sandwich disposed between the outer circumference and the inner pneumatic chamber, wherein the first cohesive sandwich comprises a first cohesive material under pressure, wherein the first cohesive sandwich is adjacent to and radially inward of the pneumatic tire; and
a diamond layer disposed between the first cohesive sandwich and the inner pneumatic chamber, wherein the diamond layer is formed from adjacent hollow blocks, each hollow block having a radially outward periphery greater than a radially inward periphery.

### Claim 2 (depends on 1)

The device of claim 1, further comprising a second cohesive sandwich disposed between the diamond layer and the inner pneumatic chamber, wherein the second cohesive sandwich comprises a second cohesive material under pressure.

### Claim 3 (depends on 2)

The device of claim 2, further comprising a plurality of spaced apart vertical septums extending from the second cohesive sandwich through the inner pneumatic chamber, defining a plurality of partitions of said inner pneumatic chamber.

### Claim 4 (depends on 3)

The device of claim 3, wherein each vertical septum provides a through hole, pneumatically connecting adjacent partitions of said inner pneumatic chamber.

### Claim 5 (depends on 3)

The device of claim 3, further comprising at least one sagittal support septum spanning between adjacent partitions of said inner pneumatic chamber.

### Claim 6 (depends on 1)

The device of claim 1, wherein the first cohesive material is a highly cohesive silicone gel-rubber layer.

### Claim 7

A device, comprising:
a pneumatic tire having an outer circumference and an inner pneumatic chamber;
a first cohesive sandwich disposed between the outer circumference and the inner pneumatic chamber, wherein the first cohesive sandwich comprises a first cohesive material under pressure;
a diamond layer disposed between the first cohesive sandwich and the inner pneumatic chamber, wherein the diamond layer is formed from adjacent hollow blocks, each hollow block having a radially outward periphery greater than a radially inward periphery;
a second cohesive sandwich disposed between the diamond layer and the inner pneumatic chamber, wherein the second cohesive sandwich comprises a second cohesive material under pressure, wherein each cohesive material is highly cohesive silicone gel-rubber layer;
a plurality of spaced apart vertical septums extending from the second cohesive sandwich through the inner pneumatic chamber, defining a plurality of partitions of said inner pneumatic chamber, wherein each vertical septum provides a through hole, pneumatically connecting adjacent partitions of said inner pneumatic chamber; and
at least one sagittal support septum spanning between adjacent partitions of said inner pneumatic chamber.
