After properly inflating my tires (new one was at 20, rest were high 20's), the replaced tire seems to be helping quite a bit. It isnt perfect but it is much, much better. It is the Goodyears, gdad is spot on. Get the Michelins, I am holding out until they replace mine. I still get the weird little shimmies at odd speeds but nothing I cant live with compared to what I experienced.
I finally sense some hope.
