Control in all circumstances for city cars.
Accurate paths and "stick-to-the-road" braking:
Directional tread pattern with two central ribs (one rib on some sizes).
The shape of the blocks stiffens the tread for greater tyre contact area.
On wet surfaces:
3 longitudinal grooves and transversal canals that direct water to the edge of the tyre.
Deep, transversal grooves for a claw effect in the wet.
