Claims20
A cured tire comprising:
- a treated, cured inner liner having a thickness of 0.5 to 2 mm, comprising rubber a majority by weight of which comprises butyl rubber and 10-100 phr of at least one filler comprising carbon black, clay, or silica, and having an upper and a lower surface wherein the lower surface is radially inward facing and further comprises silicon atoms within silanol moieties, wherein the silanol moieties are present in an amount such that a majority by weight of the silicon atoms are contained within silanol moieties,
- at least one component radially inner of the inner liner.
A cured tire comprising:
- a treated, cured inner liner having a thickness of 0.5 to 2 mm, comprising rubber a majority by weight of which comprises butyl rubber and 10-100 phr of at least one filler comprising carbon black, clay, or silica, and having an upper and a lower surface wherein the lower surface is radially inward facing and further comprises silicon atoms within silanol moieties, wherein the silanol moieties are present in an amount such that a majority by weight of the silicon atoms are contained within silanol moieties,
- at least one component radially inner of the inner liner, and
- an adhesive layer between the lower surface of the inner liner and the at least one radially inner component.
A cured tire comprising:
- a treated, cured inner liner having a thickness of 0.5 to 2 mm, comprising rubber a majority by weight of which comprises halogenated butyl rubber and 10-100 phr of at least one filler comprising carbon black, clay, or silica, and having an upper and a lower surface wherein the lower surface is radially inward facing and further comprises silicon atoms within silanol moieties, wherein the silanol moieties are present in an amount such that a majority by weight of the silicon atoms are contained within silanol moieties,
