Why won't my bike tire come off the rim?

There could be several reasons why your bike tire won't come off the rim. One common reason is that the tire may be stuck due to built-up dirt or debris. Another possibility is that the tire may be overinflated, making it difficult to remove. Additionally, the tire may be stuck due to a damaged or worn-out rim strip. It is important to carefully inspect the tire and rim to determine the cause of the issue before attempting to remove the tire.
