LOW ROLLING RESISTANCE TIRES FOR SUSTAINABLE MOBILITY
How can we reduce CO2 emissions from road traffic?
Environmental and climate protection are driving the development of modern tires. Today, road transport accounts for 15 % of total CO2 emissions, with passenger cars making up 41 % of global transportation emissions. That’s why the vehicles of the future are to consume less fuel and thus emit less carbon dioxide. The components of the tire tread have a major influence on this, as tires with a low rolling resistance save fuel.
ULTRASIL® lowers rolling resistance by up to 35 percent
ULTRASIL® combined with Evonik silanes substitutes carbon black as reinforcing filler in tire tread rubber compounds. ULTRASIL® active filler in combination with the silane Si 363™ can reduce rolling resistance by up to 35 %. The Silica/Silane system in Green Tires saves up to 8 % of fuel, resulting in a potential saving of up to 1.4 metric tons CO2e per car*. If all passenger car tread compounds worldwide used the Silica/Silane system instead of carbon black, 1,675,394,000 metric tons CO2e could be avoided. Tires with a low rolling resistance will become even more important in the future of sustainable mobility, as they can help extend the range of electric cars.

Advantages of ULTRASIL® for safe and sustainable tires:
- Reduced rolling resistance for lower fuel consumption
- Improved wet grip performance for more safety
- Highly durable even when subjected to heavy loads
- Less abrasion
- Silica/Silane system as a decisive component of Green Tires
