As we were about to leave for the office, I noticed that my rear left tire was deflated. I looked and saw a screw embedded deep in the tread. You DON’T remove embedded objects from your deflated tire so I just tried inflating the tire with my handy lighter air pump and thankfully the tire seemed to hold air reasonably well enough to let me drive to the office.
But I wasn’t about to let it stay that way for long so I left work early and went to the nearest Goodyear Servitek branch where the service guy cold patched the tire. He even replaced the missing tire inflator valve of one of my tires. As always, great service from Goodyear Servitek.
