Insert the flathead screwdriver, or another sturdy, long object, between the edge of the tire and the wheel rim.

Be careful not to damage the inner tube when inserting and moving the screwdriver or other tool. The inner tube is fragile and may be pinched between the wheel rim and tool.

Work the edge of the tire out of the wheel rim using a screwdriver, pulling the edge of the tire away from the center of the wheel and out of the rim.
