Take your bike to the shop and have them try to stick a wheel with a 2.25" tire into your frame and fork. You may find that you can only put 2.1" in your frame while your fork will probably fit a 2.5" inch or larger. If so, it is perfectactly acceptable, and recommended by some, to run a narrower tire in the rear where it will dig into mud better.
Just remember that tire sizes vary from one manufacturer to another. Also remember that smaller clearence may also dictate that you keep your wheels a tad bit truer (1mm tolerance).
