Abstract
A pneumatic tire having a component comprising: at least one rubber selected from polybutadiene rubber, styrene-butadiene rubber, synthetic polyisoprene rubber, and natural rubber; and from 1 to 30 parts by weight, per 100 parts by weight of rubber, of a terpolymer of: ethylene, an α-olefin, and a non-conjugated diene; the terpolymer having an ethylene content of greater than 80 percent by weight and a Mooney viscosity (ML 1+4 at 125° C.) of from 5 to 25 as measured by ASTM D-1646.
Claims14
A pneumatic tire having a tread comprising a plurality of ground contacting tread lugs comprising:
- at least one rubber selected from polybutadiene rubber, styrene-butadiene rubber, synthetic polyisoprene rubber, and natural rubber;
- and
- from 1 to 30 parts by weight, per 100 parts by weight of rubber, of a terpolymer of:
- ethylene, an α-olefin, and a non-conjugated diene;
- the terpolymer having an ethylene content of greater than 80 percent by weight and a Mooney viscosity (ML 1+4 at 125° C.) of from 5 to 25 as measured by ASTM D-1646;
- wherein at least part of the tread has a net-to-gross ratio of less than 50 percent.
