Tpms accuracy

Majority of the good reviews appear to be people using them a couple times a year on their 35psi passenger car tires so I take those reviews with a grain of salt.
I prefer an analog dial gauge but willing to go digital if someone has one they've had good luck with.

Go to a truck stop and purchase a Milton tire gauge. Good to 150 psi, has a two way valve for those with duals, and makes a good head knocker for protection.

Thanks powerdman! That one looks great!

I'm glad the discussion went to gauges. Saved me from having to ask the same question. I have no less than 8 tire pressure gauges. Some purchased at auto parts stores, some at places like Wal-mart. Some electronic, some stick and some analog gauge. None of them will agree. I bought one yesterday under the "Slime" label that seems to work pretty good so I'm just going to run with that one. At least I'm trying..........Right?

I have a 2004 F250, a 35' Heartland Sundance. I use TPTMS on my camper and my truck. During a camping trip last month to Jacksonville I experienced a double flat on my truck (not pulling)within 1 hour of each other due to valve stem failures. I had just purchased the tires from Firestone last August and they insisted that the tires were fitted with new stems. I have used my TPTMS for nearly a year and have not experienced any problems until now. Apparently during travel the sensors cause the stems to wobble which eventually lead to their failure. This is just an assumption. Has anyone else experienced similar failures using TPTMS and are there any recommendation on something to keep the valve stems from wobbling so I can keep using these sensors?

Metal valve stems. TST says you can use the rubber stems if they are no longer than 1 1/4" long. They still recommend metal stems though. How long are your valve stems?

Mine read within the limits of error, my digital gauge is what I trust (digital's are more accurate than dial).
Even reflected sunlight onto a tire will make a small pressure difference. That's why most TPMS users see 1-3# difference in cold readings from day to day.
Don't let a TPMS pressure difference bother you, remember 25 years ago when we never heard of a TPMS? We were happily unaware of slight pressure differences.
