The Kumho Ecsta PS71 are developed from High Dispersion Micro Silica which minimizes wearing, increases mileage and improves the handling. The steel belt reinforced structure and sidewall fortification renders the tires largely impervious to shocks, which in turn increases serviceable life. The four wide grooves drain the water away and the wide channels facilitate maximum tire to road contact, ensuring reliable wet grip.This tire pattern and size is ideal for Opel Corsa OPC and so on.
