Correct answer
Transversal and circumferential
Transverse and circumferential or longitudinal. The former cross the tread and the latter run around its circumference; tread patterns combine grooves of differing shapes and orientations to help drainage. Not every model has an identical design, and grooves cannot guarantee prevention of aquaplaning. Wear, pressure, speed and water depth also matter.
