I did my first cross race (finally!) this weekend. But I completely neglected to pay attention to my tires, and just have the ones that came with my bike - specialized tri cross comp. How do I go about choosing a new set of tires? The ones that came with the bike are too slick, I need something knobbier. I race in the midwest and there are only a few races left this season that are guaranteed to be fairly muddy and snowy.
I know my wheels are 700x32 and that I have to get the right size, but do you generally go in to a bike shop and check them out, or buy them online, how do I choose how much I should spend, which ones I should buy. I'm lost in an internet sea of cross tires and have no idea where to begin.
