    Abstract: The present invention relates to a heterogeneous silica/carbon black-filled rubber compound and a process for making the same. The rubber compound has improved (lower) electrical resistivity compared to homogeneous silica-filled rubber compounds. The process comprises(a) intimately dispersing from 30 to 60 phr of a silica filler and 5 to 80 phr of a carbon black in a first rubber to form a first nonproductive compound;(b) intimately dispersing curatives in said first nonproductive compound to form a first productive compound;(c) separately intimately dispersing from 20 to 100 phr of a silica filler in a second rubber, which is different from said first rubber, to form a second nonproductive compound; and(d) intimately dispersing curatives in said second nonproductive compound to form a second productive compound; and(e) mixing said first productive compound with said second productive compound to form a heterogeneous silica/carbon black-filled rubber compound.

    Abstract: A pneumatic radial ply tire includes a pair of beads, a single carcass ply, a tread, and a pair of sidewalls. The pair of beads each has an associated chaffer. The single carcass ply is folded about each bead so as to define a main body portion and a turnup portion associated with each bead. The tread is disposed radially outward from the single carcass ply. The tread has shoulder portions disposed at axial outer edges of the tread. The pair of sidewalls extends radially outward from each chaffer to a location adjacent each shoulder portion. Each sidewall is disposed axially outward of the single carcass ply. Each sidewall includes a first outer layer extending from the chaffer to the shoulder portion and a second inner layer extending from the chaffer to the shoulder portion. The second inner layer is disposed entirely between the single carcass ply and first outer layer. The second inner layer comprises a foamed structure of a rubber composition having a density ranging from 0.1 to 1.0 g/cm3.
