Claims20
A pneumatic rubber tire having at least one component with a visually observable outer surface comprised of a carbon black rich rubber composition, wherein said rubber composition comprises, based on 100 parts by weight rubber (phr);
- (A) at least one diene-based elastomer,
- (B) reinforcing filler comprised of
- (1) from about 20 to about 120 phr of carbon black, or
- (2) from about 5 to about 50 phr of carbon black and correspondingly about 5 to about 80 phr of precipitated silica, and
- (C) about 0.5 to about 20 phr of at least one alkanol selected from alkylphenoxypoly(alkyleneoxy) alkanol of the general formula (I):
- 2
- wherein said alkyl groups are selected from alkyl groups having from 6 to 12 carbon atoms;
- said alkeneoxy groups are selected from ethyleneoxy or propyleneoxy groups, and the number of alkyleneoxy repeat units (n) is an average of about 2 to about 60 and m is a value of 1 or 2;
- wherein said alkanol group is selected from ethanol or propanol.
