Thanks for the suggestion. It’s a tubeless ready rim but it came stock with a tubed tire. I could find no discernable weak spots around the rim that would allow me to work a lever in. I contacted Diamondback and the representative did acknowledge the Schwalbe tires can be difficult to remove. In his email he did seem to suggest that they will replace with different tires if the bike is still under warranty. Still might go to the LBS and see if they can remove it.
