I need a new set of tires, and I've narrowed it down to these two. I can get the Kumhos for $356.44 shipped and the Falkens with valve stems for $365.93 shipped. These would be used for daily driving in San Francisco and commuting about 50 miles each day, plus a little track use every once in a while. Anyways, lemme know what you guys think about these. Oh yeah, and the sizes are 215/40/16
