The real truth of this bald tire situation is that on dry pavement they actually offer more grip!!!. I read this once on the Goodyear FAQ's web site. Yes, bald tire are better. Ever notice that serious race cars run slicks. They do so to put more rubber in "contact" with the road. Treaded tires have air gaps that keep rubber off the road but provide water pumping action in the rain/snow. Your TOD issue probably is not tire related unless you were noticing it in the wet.
