Having the best traction in the rear is better for preventing a vehicle from spinning out (extreme oversteer). Losing traction at the front results in the vehicle pushing (understeer) which is much easier to control.
My comment doesn't contradict anything because the post I quoted suggested putting the older spare on the front. Organizations with a vested interest in preventing accidents due to tire failure will tell you the same thing.
