Changing tires at night

At 10:30 p.m., as we stumbled out of the pub, a man stood shaking his head in the sleet next to his VW van, a jack in hand. His left rear tire had gone flat, losing part of its tread. Naturally, we helped him mount the spare tire, albeit with far too little air pressure, although I doubted the subsequent drive to the nearest tire shop would be successful. Well, perhaps the spare tire would come off by then, and the man could buy two new tires.
While fitting the tires, I suggested to the VW bus owner that he should install a tire pressure monitoring system (TPMS), especially since he had made his bus quite heavy with his homemade chipboard conversion, particularly in the rear. He claimed that such TPMS systems only went up to 4 bar, and when I told him that NO, they were available as wireless sensors up to 11 bar and also with 6, 8, or more sensors, he refused to believe me. I gave him the website address www.TireMoni.com, where he could download datasheets and information and find out which system would best protect his bus from tire problems.
And again, I just don't get it. This guy invests time, many weekends, materials, and money into converting the interior of his VW bus, building what is—at least to him—a valuable vehicle, and then he jeopardizes it all with underinflated tires. Tire pressure monitoring is so easy these days. Retrofit with TireMoni, and you can read the tire pressure and temperature while driving. And that's not all. The system warns you with an audible signal and flashing lights if there's a slow leak. Long before the tire starts to flex dangerously, overheat, partially detach, and finally bursts, the tire pressure monitoring system alerts you, and you can react, check the tire, inflate it, and get it repaired. Long before any damage occurs.
