TPMS--------flow thru or not

Had them, weight (centrifugal) pushes them up against the rims and bends the valve stems on rubber stems on the trail, Got rid of them because of that

Went to moab last year. On my way I had two flats on my trailer in Monticello. One on the way up and one on the way home. You can not feel flat tires with these big rigs like you can with a truck, tpms is a must have.

We just installed the 1A1 system from TireMinder on our coach & Jeep. Easy install and a bit more piece of mind. We did not get the flow sensors. How often does one adjust air pressure?

The Jeep doubles as a toad & daily drive and we remove the sensors when it's not a toad.

The one thing we noticed on our 1st trip with the TPMS was how hot the front right tire on the Jeep gets. It's closest to the exhaust from the DP so I suppose that shouldn't be surprising.

Agree with what other folks have already said. I have the TST507 with flow through on the MH and standard sensors on the toad. As already mentioned, the flow through sensors are longer and having them on the Jeep toad just didn't seem wise. On the MH, they work great. I do take them off the toad when we're not on the road as those wheels are much smaller and that added weight does seem to be felt when driving at higher speeds (could be just my imagination, but why risk it?).

One should absolutely install metal stems to use the sensors. The sensor weight is enough at higher speeds to actually pull the rubber valve stems out over time.

I've had both (TST brand...great folks) and nothing but flow through from here on. When you're trying to get the exact pressure with non-flow, you air - take off sensor and check - re-air - etc. etc. I'm lazy and if I have to do all that I take short cuts.

If you're adjusting pressure with the non-flow thru type, why wouldn't you just take it off and use a regular hand gauge until you had the pressure you wanted?

You will have a difference in pressure readings from your TPS monitor and what your air gauge says, mine is a couple pounds off, which in my opinion is not going to matter.

with the flow through, you can add air and use your TPS monitor to get an "exact" reading.

I am not going to be worried about if my tires are a couple pounds off

I have the flow through and 2 of them can't be aired up - so technically they don't flow through. They monitor well enough but I have to remove them to air up which sort of makes that feature pointless. TST agreed to replace them I just haven't sent them yet.
