01. What is Tire Energy Consumption Efficiency Grading?

Hankook Tire hopes to provide useful purchasing guidelines to allow customers to evaluate the superior performance of Hankook Tire products before purchasing. Through its tire energy consumption efficiency grading system, customers can see Hankook Tire’s dedication to achieving customer satisfaction and protecting the environment through eco-friendly products with superior performance and high energy. Tire performance indicators not included on the label can be verified through test results conducted by famous car magazines and driving performance tables.

※ Hankook Tire’s eco-friendly tires can help reduce fuel consumption.

(There can be differences in fuel consumption levels based on car type, road conditions and driving habits.)

02. Outline

The tire energy consumption efficiency grading system consists of the energy consumption efficiency grade meter and the lowest energy consumption efficiency standard.

* Energy consumption efficiency grade meter: A product’s energy consumption efficiency grade is listed on a grading scale from 1-5 so customers can choose the highest efficiency products.

* Minimum requirement standard: Determines lowest possible energy efficiency level for tires to restrict production and sales of products that do not meet this standard.

03. Fuel Efficiency Indicator

RR, the acronym for ‘rolling resistance,’ is a tire function related to fuel efficiency. Rolling resistance indicates the resistance that occurs when a round object like a ball or wheel moves in a straight direction on a flat surface. This resistance occurs due to a change of the object, a change of the object’s surface or both at once. Other factors include wall radius, straight-driving speed, degree of surface attachment and the relatively subtle slippage between contact surfaces. Resistance is usually determined by the material of the wheel or tire and of the road surface.

04. Wet Grip Indicator

Wet Grip indicates braking performance and is a tire function related to safety.

Tires with weak rolling resistance are advantageous in terms of fuel consumption but can be problematic in terms of safety. This is because on wet roads, tires with weak rolling resistance have low attachment with the road surface. Thus, for the tire energy consumption efficiency grading system, wet grip indicator is listed on the label along with level of fuel efficiency.
