Definitely about sustained g's, high engine speed and track configuration...braking g's/cambered surface/connected corners. Having oil starved a Cayman S and Boxster motor to failure (rod bearings, both catastrophic, one leading to a fire), it can be fine line between moderate R tires and aggressive R tires or slicks like Hoosier A6s.
