DING!! I was headed down I-95 last Saturday evening when my dashboard announced that one of my tires had low pressure. A couple button pushes showed me a readout with three normal tires, and the right rear down to 25. I drove on as it started to rain, and eventually watched it creep down to 24 psi. What to do? It was a slow leak, so maybe I could find somewhere to add air and nurse it along? I wasn’t super stoked about doing a tire change in the rain on the shoulder of a darkening highway… On the other hand, I also could not get excited about sitting through the Orioles game wondering whether or not I would have to call AAA to Parking Lot G at 11 pm.
