Schwinn meridian three-wheel bicycle
Note that you cannot swap wheels, since the front wheel has a different hub from the rear ones.  You could presumably swap tires, but there would be little point in this unless the front tire for some reason has a much thicker tread than the rear ones.

If the brakes are rubbing on the rim it may be that the rim is warped and needs to be "trued", or it may be that the brakes are out of adjustment somehow.  (Rim brakes can be tricky to adjust.)  It's also possible that the axle is simply not seated squarely in the notches of the fork.
