Rolling resistance refers to the energy lost when the tire is moving as you drive. The lower the rolling resistance, the less energy is lost and less fuel needed. Better fuel efficiency affects positively the environment and the driver’s carbon footprint by reducing CO2 missions. For electric cars lower rolling resistance means also longer driving range.
In 2015, we set a goal for 2020 to reduce the rolling resistance of our product range by 7% compared to the 2013 baseline, thereby creating a decrease of 500 million kg in CO2 emissions from traffic. We reached this goal clearly ahead of schedule. By 2020, we had reduced the rolling resistance by 8.5% on average since 2013.
Our new goal for developing the rolling resistance of our tires is that by 2028, we aim to have at least 60 tires in the best rolling resistance A class of EU Tyre labeling system.
TIRE'S MOST SIGNIFICANT ENVIRONMENTAL IMPACT: FUEL CONSUMPTION DURING DRIVING
Carbon dioxide is the most significant greenhouse gas generated by traffic. Fuel consumption during driving is the single most significant environmental impact over a tire’s service life.
We have managed to reduce the rolling resistance by improving tire constructions and compounds, among other things. We are also utilizing the latest functionalized polymers to reduce hysteresis losses and rolling resistance.
Around 90% of Nokian Tyres’ tires are in the best rolling resistance categories A, B or C. This translates to an annual decrease of over 100 million kg in CO2 emissions.
The difference is significant for a car owner – and not just environmentally. A class A summer tire that has a correct tire pressure can save up to 0,6 liters of fuel per 100 kilometers compared to the lowest performing tires.
In the end, eco-friendliness in traffic comes down to a very simple fact: the driver has all the power to make a positive impact. Approximately 83% of a tire’s carbon footprint is created during its use. A wise choice of tires, the right tire pressure, and a careful driving style significantly reduce the CO2 emissions from driving.
