TPMS. Necessary or just peace of mind?

TPMS is peace of mind. Of course, that means you need to check the tire pressure on a regular basis with a tire gauge. Also, you can bump each tire with a hammer for a rough idea of tire pressure. When I got a nail in one of my duallys, the hammer test is how I found out it was losing pressure. If one of the tires loses 10 psi, you can really tell the difference in sound long before the tire goes flat. But you STILL need to use a tire gauge on a regular basis.

If you have a TPMS that has proven to be accurate, why do you need to check the tires with a pressure gauge? You can check ALL tire pressures at a glance on the TPMS display.
I checked mine regularly when I first got my TST system, but when the readouts were consistently within 1psi of the gauge reading I figured that was good enough.

I agree. Takes less than a minute to check the pressure in all 10 of my tires before each trip and several times during a trip. I say BS to those who claim to check pressures before every trip and every two hours during a trip with a pressure gauge. Plus it does not matter how careful you are you always lose some air each time you check with a gauge and take the chance of a Schrader valve not sealing after the check.
