i am trying to change the tire?

Once they rust on, they are really hard to get off. If you have a torch you may put some heat on it. If not I'v gotten them off by soaking the axle with a good penetrating oil like PB Blaster. Then find a long bolt the same thread as the one that holds the wheel on. thread this in the axle and hit it while you pul on the wheel. It helps if you have someone to put pressure on the wheel while you hit it. Be careful not to smash the threads.
