We were bewildered, not knowing what to do. The resulting debris is referred to as an 'alligator' here. https://www.sttc.com/where-do-road-alligators-come-from/ The site might be biased since they're retreaders. I don't know if it was legislation or economics but there used to be retreaded passenger car tires but for big trucks retreads are widely used , usually on the trailers. Theoretically you're supposed to check the inflation daily but with 18 tires the common practice is to 'thump' them. A 6-cell Maglite is good for that. The correct inflation is 100-110 psi but a tire down to 60 psi still sounds the same. It has to be really low before you get sort of a dead sound. I haven't driven in 30 years so I don't know if TPMS are common now. They're certainly available https://www.noregon.com/commercial-tire-pressure-monitoring-systems/ Even in the '90s a new 22.5 tire ran about $275 so getting the most life out of them made sense.
