Using tire levers, remove the tire by wedging the tire tool between the tire and rim, and then prying upward to lift the tire away from the rim.
Keeping the first tool in place under the tire, repeat this step about four inches away with the second tool to pull more of the tire over and off the rim. Repeat this step as you work your way around the rim. The one edge of the tire you’ve been working on should start to come free of the rim quite easily. You can finish this step by simply sliding the lever underneath the tire the rest of the way around the rim.
