Its an MTD ride-on - MTD dont use a key to drive the wheels the shaft has 2 flat sides.

Pretty much the tyres are stuck rusted on, there is nothing more I can do to get them off apart from buying a $10000 puller.

So I was just hoping some one would have experience with changing tubes or tyres without actually removing the rim.
