What's More Accurate?
So I finally got around to installing my TST-510 TPMS today. I've had it for about 9 months so far and just haven't gotten a "round tuit" to put the sensors on and program the system. Everything wen...

Follow-up after the first trip with the TPMS installed:
Although according to two separate gauges, one analog and one digital, all tires were inflated to 100psi cold, the TPMS showed that each was either 94, 95, or 96psi cold and it showed ambient temperatures in all tires. So, using relativity as the guide, I watched as I rode and the pressures increased equally by an average of 12-15psi. Temps shown never got above 104 degrees F according to the TPMS during this fairly short trip of around 30 miles at 65mph. Verified surface temps of the treads and sidewalls once we reached our destination with laser thermometer showing just slightly higher (on average about 5-10 degrees warmer) than the TPMS reading, although I'm fairly sure they had cooled down a bit after coming off the interstate until finally parking at our campsite for the weekend. When it was time to pack up and head home, the TPMS showed all tires back to their original starting pressures (from when we left home) and ambient temps, so I felt confident that all tires were good to go.
Overall, I like the peace of mind the TPMS gives me, knowing that there is something "watching" all of my tires for indications of failure. And hopefully I can avoid any future blowouts by heeding it's warning features. I will not use it was the absolute in actual tire pressures due to having two separate gauges (actually three if you count the one on my inflation nozzle) indicate that there was 100psi in all tires and the TPMS indicated an average of 5 psi less. It does, however, give me a relative indicator on what the tires are doing and I can set the warning indicators to match the parameters that will hopefully keep me on my toes in case something starts to go wrong.
For reference, the system I have is the TST 510rv with 6 wheel sensors installed and using the included stubby antenna.
