121T Pattern

1) Newly designed tread pattern with three grooves
improve rolling resistance and reduce external noise.
2) Wavy grooves
maximise wet and snow traction and minimise stone holding.
3) Concave shallow groove
provides additional wet and snow traction.
4) Step grooves

reduce bit and damage.
5) Rigid shoulder ribs with shallow design groove
improve shoulder step-down and straight driving stability.
