Abstract
Abstract A tire having a core located in a tire cavity and a cured and foamed elastomeric material located in the tire cavity adjacent the core. The core is made of a solid material, a precured and foamed elastomeric material or a hollow rigid structure. The core may be a single piece or fabricated from multiple pieces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A method of filling a cavity defined by a cured tire casing, the method comprising: inserting a precured and foamed elastomeric material core in the cavity of the cured casing; positioning a first piece of curable and foamable elastomeric material inside the cavity between the core and the casing; positioning a second piece of curable and foamable elastomeric material inside the cavity between the core and a tire centerline; and heating the filled cured tire casing for a heating time to cure the first and second pieces of curable and foamable elastomeric material to substantially encapsulate the core and fill the cavity between the core and the casing with a closed cell foam rubber composition.
Claim 2
Independent Claim
115 words
A method of filling a cavity defined by a cured tire casing, the method comprising: inserting a precured and foamed elastomeric material core in the cavity of the cured casing; positioning a first piece of curable and foamable elastomeric material inside the cavity between the core and the casing; positioning a second piece of curable and foamable elastomeric material inside the cavity between the core and a tire centerline; and heating the filled cured tire casing for a heating time to cure the first and second pieces of curable and foamable elastomeric material to substantially encapsulate the core and fill the cavity between the core and the casing with a closed cell foam rubber composition.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein the first and second pieces of curable and foamable material are so dimensioned to reduce the heating time in comparison with a heating time to cure a tire containing only curable and foamable elastomeric material.
Claim 4
Dependent Claim
32 words
The method of claim 1 further comprising: placing at least one additional piece of curable and foamable elastomeric material inside the cavity between the core and a sidewall of the tire casing.
Claim 5
Dependent Claim
36 words
The method of claim 3 further comprising: placing at least one additional piece of curable and foamable elastomeric material inside the cavity between the core and a casing wall below a tread of the tire casing.
