## Abstract

A method of manufacture of a wheel with a tyre 2 in which the tyre 4 is formed directly on the wheel in which the wheel has a conduit which runs between its hub and rim, and a mould is placed over the wheel in order to form a cavity between an inner surface of the mould and the wheel's rim. Liquid materials to form the tyre 4 are injected into the cavity via the conduit and the wheel spun to distribute the materials throughout the cavity, which materials solidify to form the tyre 4 attached to the wheel. The method includes the step of placing a hub cap 6 over a face of the wheel prior to placing the mould and sealing the hub cap 6 to the wheel during the moulding process. The invention also relates to a wheel manufactured according to said method.

## Claims

### Claim 22

A method of manufacturing a wheel and a tyre comprising the steps of providing a wheel and moulding a tyre to the wheel, placing a mould over the wheel such that a cavity is formed between an inner surface of the mould and a rim of the wheel, for receiving material to form the tyre, wherein the wheel is provided with an inlet which is fluidly connected by a conduit to an outlet in the rim of the wheel, and a material to form the tyre is injected into the inlet, and wherein a hub cap is provided and the method includes the additional steps of covering a face of the wheel with the hub cap prior to the step of placing the mould, and sealing the hub cap to the wheel during the moulding process.

### Claim 23 (depends on 22)

A method according to claim 22, wherein a hub cap is placed on each face of the wheel prior to the step of moulding.

### Claim 24 (depends on 22)

A method according to claim 22, wherein the hub cap extends to at least partially cover the rim.

### Claim 25 (depends on 22)

A method according to claim 22, wherein the hub cap has a plurality of apertures and the method includes the step of aligning the apertures with the outlet to fluidly connect the apertures with the outlet.

### Claim 26

A method of manufacturing a wheel and a tyre comprising the steps of providing a wheel and moulding a tyre to the wheel, placing a mould over the wheel such that a cavity is formed between an inner surface of the mould and a rim of the wheel, for receiving material to form the tyre, wherein the wheel is provided with an inlet which is fluidly connected by a conduit to an outlet in the rim of the wheel, and a material to form the tyre is injected into the inlet, and wherein a hub cap is provided and the method includes the additional steps of covering a face of the wheel with the hub cap prior to the step of placing the mould, and sealing the hub cap to the wheel during the moulding process, wherein the hub cap has a plurality of apertures and the method includes the step of aligning the apertures with the outlet to fluidly connect the apertures with the outlet, and wherein the rim has a first open channel and the outlet opens into the first open channel, the step of placing the hub cap further including the step of covering the first open channel with the hub cap whilst aligning the apertures of the hub cap with the first open channel.

### Claim 27 (depends on 26)

A method according to claim 26, wherein a second open channel is provided in the rim which is fluidly connected to the first open channel.

### Claim 28 (depends on 26)

A method according to claim 26, wherein a second open channel is provided in the rim which is fluidly connected to the first open channel, and wherein the first and second open channels open to opposite faces of the wheel.

### Claim 29 (depends on 26)

A method according to claim 26, wherein the rim compromises two spaced concentric bands interconnected by a web between the bands, which bands extend around the circumference of the wheel, wherein the open channel is provided in at least one of the bands, the step of placing the hub cap further includes the step of sealing the web between the bands with the hub cap.

### Claim 30 (depends on 26)

A method according to claim 26, wherein the first open channel is in the innermost band and the method includes the step of introducing material to form the tyre into the inlet, flowing the material through the conduit into the open channel, flowing the material through the apertures into the mould's cavity and allowing the tyre to form in the cavity.

### Claim 31 (depends on 26)

A method according to claim 26, wherein the first open channel is in the innermost band, and wherein a second open channel is provided in the innermost band which is fluidly connected to the first open channel, and the method further includes the step of introducing material to form the tyre into the inlet, flowing the material through the conduit into the first open channel, flowing material from the first open channel to the second open channel and flowing the material through the hub cap apertures into the cavity and allowing the tyre to form in the cavity.

### Claim 32 (depends on 26)

A method according to claim 26 wherein the mould is placed over the wheel and extends substantially around the circumference of the wheel encapsulating the rim, the cavity defining the shape of the tyre to be moulded about the rim, wherein the material to form the tyre is introduced into the mould in a liquid form and allowed to solidify in the mould, conduit, channel and apertures to form a tyre and anchor the formed tyre to the wheel.

### Claim 33 (depends on 22)

### Claim 35 (depends on 26)

A wheel with tyre according to claim 26, wherein a hub cap is placed on each face of the wheel prior to the step of moulding, each hub cap extending to at least partially cover the rim, and each hub cap having a plurality of said apertures and the method includes the step of aligning the apertures with the outlet to fluidly connect the apertures with the outlet.

### Claim 36

A wheel with tyre wherein the wheel has a rim and opposite faces, and the tyre is moulded about the rim by placing a mould over the wheel such that a cavity is formed between an inner surface of the mould and the rim of the wheel, the wheel for this purpose having an inlet which is fluidly connected by a conduit to an outlet in the rim, whereby material to form the tyre is injected into the inlet, the wheel with tyre further having a hub cap sealed to a face of the wheel by the moulded tyre during the moulding of the tyre, and wherein the tyre has a substantially hollow interior.

### Claim 37 (depends on 36)
