Any water or grit flung off the tire will travel tangentially, i.e. prependicular to the wheel radius. That's why you often need to attach a mud flap on the end of the front fender if you want to keep water off your feet, and on the rear fender to keep spray off any riders behind you. Back when I was doing a lot of training here in Vancouver, anyone who showed up for a winter group ride without mud flaps would get an earful.
