Earth-1 adops a newly-developed compound with Orange Oil.
The newly-developed compound with Orange Oil is the aggregation of our ECO tire technologies. It is a new-generation ECO tire ir which reduction of rolling resistance
achieves a good balance between high fuel efficiency and wet performance.
Controlling heat necessary for grip at a higher level
Our twin mode concept is to control each tire's temperature during
hard or normal diving. "Orange Oil" promotes heating at the time
|
of hard driving when rubber molecules of a tire move vigorously, achieving a balance between the reduction of rolling resistance and good grip force.

New patterns achieve the quietness at a high level
|
Earth-1 adopts three different sizes and two different shapes-a total of six different types of block. Dispersing impact noise made when blocks contact the ground reduces pattern noise.

Wear control shoulder controls uneven wear.
The wear control shoulder controls uneven wear and contributes to quietness when wer is caused. The rigib rib positioned at the inner side of each block firmly supports load during cornering to control uneven wear. Uneven wear on a single shoulder block results in more noise, while the rib promotes even wear to keep noise levels low when wear occurs.
The arrow-shaped groove ensures good drainage
The arrow groove adopted in the tread pattern ensure good drainage and the vertical block in the circumferential direction ensures rigidty when braking, which improves wet performance.

Wide straight grooves provide high wet performance
These four straight grooves control hydroplaning on wet roads
