The morning after I finished the last 300 mile leg home, I checked the tire pressures. One inside dually read zero. I limped to my dealer where I bought my 'C' and had both tires on that side replaced. I had no idea when the tire ran over that huge nail. Then I had a TPMS monitoring system installed. I also carry a mounted spare in the storage area. To make room, I removed the entire set of metric tools I was carrying around for some unknown reason.
I figure that heavy duty tow trucks can lift my 'C' off the ground, but the chances of them having a replacement tire are pretty slim.
