Claims4
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.
