Kumho tires are manufactured in South Korea. China. and Vietnam.

Hankook Tire & Technology, a South Korean company, has a global manufacturing footprint. Initially, production was concentrated in South Korea, but to meet international demand and reduce logistics costs, Hankook expanded its manufacturing base. It now operates several plants worldwide, including in China, Hungary, Indonesia, and the United States. The plant in China focuses on serving the vast Asian market, while the facility in Hungary caters to European demand. Indonesia's plant supports both domestic and Southeast Asian markets. The United States plant, located in Tennessee, was established to manufacture products specifically for the North American market, highlighting Hankook's strategy to localize production and shorten supply chains. This global distribution of manufacturing facilities not only helps Hankook mitigate risks associated with reliance on a single market but also allows for faster response times to changes in demand within these key regions.

Cleaning valves on a direct injection (DI) engine requires special attention due to the design limitations of DI systems, where fuel is directly injected into the combustion chamber, bypassing the intake valves. This means traditional fuel additives won't clean the valves as they do in port injection engines. Over time, carbon deposits can accumulate on the valves, leading to decreased performance and efficiency.

One effective method for cleaning valves in a DI engine is walnut blasting. This involves using pressurized air to blast walnut shell granules at the valves, effectively removing carbon deposits without damaging the valve material. It's an environmentally friendly and highly effective technique but requires special equipment and should preferably be performed by a professional.

Alternatively, chemical cleaners designed for DI engines can be used. These are introduced directly into the intake system and require following the product instructions carefully to avoid damage. Some products are designed to be used with a running engine, breaking down deposits that are then expelled through the exhaust system.

Regardless of the method chosen, it's crucial to regularly perform this maintenance on DI engines to prevent long-term issues and preserve engine performance. Consulting the vehicle's service manual or a professional mechanic for recommendations on cleaning frequency and methods is advisable. Regular cleaning not only contributes to the longevity of the engine but also maintains its efficiency and performance.
