Abstract
A pneumatic tire comprising non-ground contacting tire components each independently formed from a rubber composition comprising greater than 89% sustainable material content.
Claims23
A sustainable tire formed from tire parts comprising at least one each of a tread, plycoat, wirecoat, sidewall, chafer, toeguard, gumstrip base, apex, overlay and beadcoat:
- wherein the tire parts are each formed from a diene rubber composition comprising a mass-balance synthetic polymer;
- wherein the diene rubber is present at greater than 35% by weight in the tire;
- and
- wherein the tire is formed from greater than about 85% by weight of content made from processes or technologies that reduce carbon emissions and/or resource consumption, and/or recycled, renewable, bio-based, bio-derived, and mass balance raw materials;
- wherein the bio-based content of the tire is verifiable, and wherein radiocarbon 14C dating according to ASTM method D6866 shows the tire to have a bio-based content of greater than 85%.
A pneumatic tire formed from a first rubber compound and a second rubber compound, each of the first and second rubber compound being independently incorporated in a non-ground contacting tire component, each of the first and second rubber compounds comprising, based on 100 phr of rubber polymer:
- at least one rubber polymer selected from a group consisting of mass balanced SBR;
- natural rubber;
- mass balanced polybutadiene;
- and mass balanced synthetic polyisoprene;
- a bio-based oil;
- an optional filler comprising sustainable carbon black or rice ash husk silica;
- wherein a total percent of renewable content in the first and second rubber compounds is greater than 80%.
A sustainable tire formed from tire parts comprising at least one each of a tread, plycoat, wirecoat, sidewall, chafer, toeguard, gumstrip base, apex, overlay and beadcoat:
- wherein the tire parts are each formed from a diene rubber comprising natural rubber and/or mass-balance synthetic polymer;
- wherein the tire parts are produced from at least four different carbon blacks derived from methane, carbon dioxide, plant-based oil and end-of-life tire pyrolysis oil feedstocks;
- wherein the carbon blacks are present at greater than 15% by weight in the tire;
- and
- wherein the tire is formed from greater than about 85% by weight of content made from processes or technologies that reduce carbon emissions and/or resource consumption, and/or recycled, renewable, bio-based, bio-derived, and mass balance raw materials.
A sustainable tire comprising a toroidal-shaped carcass, two spaced, beads and sidewalls extending radially from and connecting a tread to the beads, the tire formed from rubber compositions comprising:
- at least a mass-balanced SSBR in the tread;
- at least a mass-balanced polybutadiene in the sidewall;
- at least a mass-balanced ESBR in the bead coat;
- wherein each of the tread, sidewall and bead coat are formed from greater than about 85% by weight of sustainable content made from processes or technologies that reduce carbon emissions and/or resource consumption, and/or recycled, renewable, bio-based, bio-derived, and mass balance raw materials.
