Tires won’t come off rims Help!
Have a Diamondback Release with Schwalbe Hans Dampf tires on Blanchard rims.  Couldn’t break bead to get tires off as I wanted to convert to tubeless, even after trying tire levers for an hour with hot soapy water as a lubricant. In the end, I had to get a bike shop to do it for me.

Is this a common problem with these rims or tires.  This isn’t good.  What if you were trailside and needed to work on your tire? Is there a tire that would come off using your hands without having to take rims to dealer?
It may be that your rims are "tubeless ready" which means they have a lip around the side that the tyre slots into which makes an airtight seal but does make them harder to get off. You should be all right if you let the tyre down completely and then push the edges of it towards the centre with your thumbs to pull it out of the slot. Once a bit of it's free the rest will usually pull out easily.
