When I was running winter tires on my civic years ago I would get some wicked wheel hop while spinning due to ice and snow at 55psi, dropped it down to 45ish and the wheel hop went away. Traction during a slide may have gone up (butt-o-meter not any skid testing) but I did not note any significant difference in traction while not skidding (which matches the science I have seen regarding tire pressure and traction). Nor did I note any mileage change as during the winter road conditions and driver technique totally wipe tire pressure rolling resistance changes away.
