TPMS

[dentmac]

Hi,
After having TPMS for the year, I suggest that everyone should have them.
I have a TST system with flow thru valves and a range extender. It is excellent but I have no comparative. I have replaced a couple of batteries but no big deal. I don't know how old the batteries were when I purchased the units.
Because the unit is outside the wheel, I don't think the temperature readings are much more then ambient temps-- still interesting , showing the sun differential and I hope with high tire temps, a warning would be given.
Most surprising is the pressure increase with driving and temps. A 25 psi increase is usual.
I have my front set at minimal 105 so on a cold morning the alarm warms you of 105 PSI. After a mile, it goes away. (I could set it lower but that is minimal pressure required for my weight)
I have let a LITTLE air out via the valve stem and the alarm goes off warning of rapid air loss. Happy with that.

If you are are changing drive tires, suggest reversing outside wheel tire stem. On the front , I think that they stick out too far so I used 90 degree extenders and stainless wire to keep them "In line" with the wheel circumference.
