Kumho Tire is leading the eco-friendly tire industry by developing low-wear, low-carbon tires that reduce fine dust and carbon dioxide (CO2) emissions.

The 'WATTRUN VS31' tire, developed by Kumho Tire using eco-friendly technology, achieved a wear performance index of 560, securing the highest competitiveness in its product group. It also received a top grade for both fuel efficiency, which reduces greenhouse gas (CO2) emissions, and braking performance for safety. The tire's weight was reduced by 30% compared to previous products, saving resources, and the use of zinc oxide was cut to less than half, minimizing environmental impact.

In tire technology development, wear performance and fuel efficiency are often at odds. It is extremely challenging to improve wear performance while also meeting the top grade for energy efficiency. Kumho Tire overcame this by creating a new synthetic rubber that enhances both wear and fuel efficiency. Additionally, by using highly dispersed and high-strength fillers, wear and fuel efficiency were improved, and a lightweight, high-strength structure was applied to reduce the weight by more than 30% compared to previous products.

Furthermore, when designing tire structures or patterns, performance prediction tools were utilized to develop pattern design technology that simultaneously enhances wear, fuel efficiency, and braking performance. Improved wear performance reduces fine dust emissions, while better fuel efficiency increases a vehicle's mileage and reduces carbon dioxide emissions.

The eco-friendly tire market continues to grow due to greenhouse gas reduction regulations in the European Union and other countries worldwide. The market for eco-friendly tires is also expected to expand alongside the growth of the eco-friendly vehicle market. Until last year, eco-friendly tires accounted for only 5% of the total tire market, but this year, their share is expected to exceed 10%.

This also benefits consumers. Although eco-friendly tire products are priced 10?15% higher than regular products, considering the longer replacement cycles and fuel savings, they are much more economical. They help reduce fine dust and fuel consumption, contributing to environmental protection.

According to a comparison by the Korea Automobile Research Institute, Kumho Tire's eco-friendly tires reduce fuel costs by about 48,900 KRW per 12,000 km per vehicle compared to standard tires. The greenhouse gas reduction effect was also measured at 50.204 kg per vehicle, which is equivalent to the amount of carbon dioxide absorbed by 12 kg of pine trees in one year.
