I've been remiss in my updates. The reason I went back was to track down a REALLY slow leak. I need to air the tire after 2 or 3 months. They tried to solve the problem for an hour. It turns out the finish on the bead side of the wheel is getting some corrosion. They tried using sealant and there is still a trace of bubbles. It's been a little over a month though and still no low pressure warning.
