On the Rear, always

There’s enough weight up front that under braking, the nose is gonna dig, so those tires are gonna put down some traction no matter what, just from that weight shift. The rear is light, and without enough traction, it goes slip slop swoopty doo into the ditch. Rear wheels keep you “tracked” to the direction of the fronts, so if you can’t stay tracked, then you slippy slide.
