On some of the mowers there is a slot on the axle and on the inside of the rim that a metal key goes in. you line up the two slots and put this key in and then tighten the wheel. it locks the rim to the axle. i am guessing it must have fallen out when you took the tire off. find it and put it back in you should be good to go.
