Has anyone else experienced problems with their TST system giving them really bad readings in cold weather or rain? We just returned from a trip to Yosemite and on the way back tire pressure reading on all four tires began to drop and then the alarm sounded. It was only about 65 degrees, but it had been much hotter, and it was raining pretty hard. I pulled over under an overpass on I-10 to check all four tires and they looked okay to me and I thumbed them all and they sounded okay to me. We pulled further down the road and the rain stopped so we pulled in to a station to check the pressure on each tire. They were all around 80 psi which is where I want them. We had been on the road for hours so it's not like we just started either. Just wondering if there is a problem with the system if it's raining or if the temp drops sharply because of weather conditions. The system functioned well, I think, all the way out to our destination from Phoenix, AZ. By the way, we have the system that you can add air without removing the stem, cannot remember if that is the 507 0r the 510.
