Solution to slash carbon footprint and costs, preserving tread performance

Cray Valley has a long history with tire manufacturers, focusing on excellence in tire compounds, especially in the tread area, for over 30 years. In response to customer demands for new developments and sustainability, Cray Valley has developed a new grade that meets several key factors: customer constraints, final product performance, environmental impact and cost. The new grade, which is in the final stage of homologation, offers 20% less CO2 emissions, 50% less water consumption and nearly 10% less fossil resource depletion. It ensures customer satisfaction and matches the performance of existing grades while reducing costs.
