old school observation.... tire whacker
Observed this weekend...18 wheeler operator using a metal rod , strolled around his rig... whacked each tire. No TPMS, no digital tire pressure gauge. The man makes a living driving big rigs. Hm...

The other alternative to thumping is the temperature of the tire.
Warning some times they can be hot enough to burn your hand, that is why I use a lasser thermometer, the hot tire is the one with the low air or some other problem and yes there is a slight variation on the temps from tire to tire, the ones exposed to the sun and the ones that are inside the duallis are different in temp but only slight, after a few trips you will be able to read the whaker sound or the temp fairlly acuratelly.
I also check the toads sound and the temp.
