Pneumatic tire with tread containing three elastomers |
| abstract |
The present invention discloses a pneumatic tire having a tread comprising three elastomers. A pneumatic tire comprising a vulcanizable rubber composition, the vulcanizable rubber composition comprising: 1) 100 parts by weight of an elastomer comprising 25 to 35 phr styrene-butadiene rubber, 45 to 75 phr phr of polybutadiene and 5 to 15 phr of natural rubber or synthetic polyisoprene, wherein the styrene-butadiene rubber is functionalized and has a Tg ( A); the natural rubber or synthetic polyisoprene has a Tg(B) of -60°C to -70°C; and the polybutadiene has a Tg(C) of -110°C to -90°C cis-1,4-polybutadiene with Tg(A)-Tg(B) ≥ 25°C and Tg(B)-Tg(C) ≥ 25°C; 2) 70 to 100 phr silica 3) 1 to 20 phr of carbon black; 4) 1 to 15 phr of rubber processing oil; and 5) 5 to 50 phr of at least one hydrocarbon resin and rosin derived resin having a Tg > 20°C. |
