You need the right tools for the job...

If you have 2-piece Lock rings you need a tool like this

The first step is to remove the valve stem core. Then break the bead on the lock ring side using a duck bill hammer

or a slide hammer

Then push the lock ring down and hook the lock ring iron into the slot on the ring and pull back on the handle. I find it helps to hit the lock ring on the other end with a heavy rubber faced hammer while pulling. The ring will pop free. Then turn the wheel and tire over and break the bead on that side, then set it on a cinder block and push the tire off of the wheel while pushing the valve stem in.

That's it!
