"OK ... I'm new at this, and I appreciate the
importance of proper inflation. But short of damage to a tire I would
think daily checking of PSI is more of a cause for air loss. Or is there
something I'm missing? There seems to be a real fixation on this
topic. I doubt school bus drivers place as much emphasis on this topic as RVers do."
You're correct. Too many fixate on daily air checks. In years gone by that was the best method we could use, but sticking valves
can cause air loss and it is not unheard of for a tire to start leaking air right after an air check.
This post shows just how easy it is for a piece of grit to get into the actual valve core opening and could allow air to leak out slowly.
To me avoiding this potential issue is one of the major advantages to using TPMS, but for some reason I have never heard anyone mention this benefit. Since I run TireTraker TPMS I don't do a manual
air check unless the readings go below the normal variation range of 3
to 5 psi around my "Set" pressure of 72 psi. Other than the start of my
travel season, I may only do a manual check once a season.
if you don't want to run a warning system then a manual check each
travel day is the only way you can know there is a slow leak. Now to me running without a good TPMS would be much like driving without any gauges or warning lights on your dash. Would you feel comfortable if this
wait till your "thumper"
makes you suspect low pressure you are getting about as much information as checking engine oil by banging on the oil pan with a hammer.
If your IR
makes you suspect high temperature you may already be too late and
might have done permanent structural damage to the tire and shortened
its life by many months or even years. Rubber is not a good conductor of heat so you will almost certainly not get the reading from the hottest location.
Just as there were advances in early cars when the temperature gauge was just a thermometer stuck in the top of the radiator,
