  • Pneumatic tire comprising polyisoprene rubber and alkali metal alginate in at least tread portion thereof adapted for travelling on frozen roads
    Patent number: 4166052
    Abstract: A rubber composition containing polyisoprene rubber or a blend of polyisoprene rubber and polybutadiene rubber has a high friction coefficient against the frozen road surface due to the easy deformability at low temperature and high affinity for water. A pneumatic tire comprising a tread consisting of the rubber composition is excellent in the brake, traction and cornering performances and can travel safely on frozen roads without the use of spikes or a chain.
