I'd love to hear from those who opted to replace the stock Hankooks with something else. My car is new, so the Hankooks still grip well, although I find the ride pretty jittery and bumpy with these tires. I really want to replace them (either with snow tires, or just good all-weather tires; I'm thinking specifically of the Continental PureContact since they seem to get great reviews and are rated really good in the snow; but I'm open to suggestions). If you chose to replace the Hankooks, what was your new tire of choice? What positive changes did you notice (smoother ride, better traction, improved mpg, etc)?
