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...

Learned this in '67, working for Kent School District. I checked 45-50 buses every morning before they rolled. Still do it (usually) on my current TV and RV.
