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...

That's another reason OTR truckers carry them. Its their only defense that is not illegal. If anyone gets any ideas, forget it. Most truckers know that a well inflated tire and an empty head sound about the same.
