The sipes on the outer shoulder of the treads helps enhance its handling capabilities and lower levels. The asymmetrical design functions as a strong base for fortifying road grip. The treads are constructed from a specialized silica compounds, which combined with the dual central grooves design helps in increasing aquaplaning resistance. This in turn reduces rolling resistance for increased mileage and improved wet road handling performance.This tire pattern and size is ideal for Opel Astra and so on.
