2009 Chevrolet Equinox Alloy Wheels

You need to remove the tire from the wheel for inspection and repair, then fill the injury (puncture) to keep moisture out, and seal the inner liner with a repair unit to prevent air loss.

First, deflate the tire completely and use the tire changer to remove the tire from the wheel. Next, apply lubricant to the tire and the wheel rim and inflate the tire to the proper air pressure.

You should spread the beads and mark the puncture with a tire crayon, next inspect the inner tire for any signs of internal damage, then remove the puncturing object, noting the direction of the penetration, probe the injury with a blunt awl to determine the extent and direction of the injury, remove any loose foreign material from the injury.
