Deflating the Tire
Deflating the Tire
Before removing the tire from the wheel, use a valve core removal tool to remove the tire valve core and deflate the tire completely. If the tire is to be patched and reinstalled without balancing, be sure to mark the locations of the valve stem and any wheel weights with a marking crayon. If another tire is to be installed on the wheel, remove any wheel weights from the wheel first.
Never attempt to break down the beads of an inflated or partially inflated tire.
