1. A method comprising: mixing a filler including silica and a bio-based oil including a soy polyol to form a filler mixture, the weight ratio of silica to the soy polyol being 1.5 to 2.5; andmixing the filler mixture with an elastomer to form an elastomeric composition, the elastomer being present
1. A method comprising: mixing a filler including silica and a bio-based oil including a soy polyol to form a filler mixture, the weight ratio of silica to the soy polyol being 1.5 to 2.5; andmixing the filler mixture with an elastomer to form an elastomeric composition, the elastomer being present in an amount less than 25 weight percent of the elastomeric composition. 2. The method of claim 1, wherein the first mixing step includes mixing the filler including silica, the bio-based oil including the soy polyol, and a petroleum-based oil present in an amount of less than 25 weight percent of the elastomeric composition. 3. The method of claim 1, wherein the bio-based oil further includes a soy oil. 4. The method of claim 1, wherein the first mixing step includes mixing the filler including silica, the bio-based oil including the soy polyol, and an epoxidized oil present in an amount of less than 25 weight percent of the elastomeric composition. 5. The method of claim 1, wherein the soy polyol has a hydroxyl number of from 10 to 350 KOH/g. 6. The method of claim 1, wherein the first mixing step includes mixing the filler including silica, the bio-based oil including the soy polyol, and carbon black. 7. The method of claim 1, wherein the first mixing step includes mixing the filler including silica, the bio-based oil including the soy polyol, and an ancillary filler. 8. The method of claim 7, wherein the ancillary filler is selected from the group consisting of soy protein, soy flour, soy meal, soy hull and combinations thereof. 9. The method of claim 1, wherein the weight ratio of silica to soy polyol is in the range of 1.7 to 2.3. 10. The method of claim 1, wherein the weight ratio of silica to soy polyol is in the range of 1.9 to 2.1. 11. The method of claim 1, wherein the first mixing step includes mixing and rolling the filler including silica and the bio-based oil including a soy polyol to form the filler mixture. 12. The method of claim 1, wherein the first mixing step is performed in a mixer. 13. The method of claim 1, wherein the first mixing step is carried out at a starting temperature and proceeds to an ending temperature greater than the starting temperature. 14. A method comprising: mixing a filler including silica and a bio-based oil including a soy polyol to form a filler mixture, the weight ratio of silica to the soy polyol being 1.5 to 2.5;mixing the filler mixture with an elastomer to form an elastomeric composition, the elastomer being present in an amount less than 25 weight percent of the elastomeric composition; andcuring the elastomeric composition to obtain a cured elastomeric composition. 15. The method of claim 14, wherein the weight ratio of silica to soy polyol is in the range of 1.7 to 2.3. 16. The method of claim 14, wherein the weight ratio of silica to soy polyol is in the range of 1.9 to 2.1. 17. A method comprising: mixing a filler including a precipitated silica material and a bio-based oil including a soy polyol to form a filler mixture, the weight ratio of precipitated silica material to the soy polyol being 1.5 to 2.5; andmixing the filler mixture with an elastomer to form an elastomeric composition, the elastomer being present in an amount less than 25 weight percent of the elastomeric composition. 18. The method of claim 17, wherein the weight ratio of silica to soy polyol is in the range of 1.7 to 2.3. 19. The method of claim 17, wherein the weight ratio of silica to soy polyol is in the range of 1.9 to 2.1. 20. The method of claim 17, wherein the filler further includes carbon black.
