you can do it, and people do, but I personally would not run the same size tire on all 4 factory rims. This is because you have to remember, the factory rims are not the same size, the rear are wider. If you try and fit the same size tire on 2 different sized (width) rims, you don't get the same riding height all the way around. Most tires have 2 widths, front/rear, just get the appropriate sizes. And like other have said, the spare will work for any size, as long as the offset of the rim is right.
That being said, I run the same tire on all 4 corners! However, that's because I got 4 identical aftermarket rims - this means same tire size on all the same rim sizes.
hope this helps.
