North America currently accounts for 20 per cent of Kumho's global tyre sales, and its new plant is intended to focus on ultra-high performance products for premium brand vehicles, elevating the company's status within the US market. The aim is also to strengthen Kumho's OEM business in the region, which has already received a boost, according to the manufacturer. Kumho states that it has negotiated significant new contracts with nearby prestige car makers ahead of production commencing. Assuming successful sales for Kumho and a continued improvement in the US economy, two further phases are planned for the Macon factory, offering the potential to as much as triple its capacity.
