Pressure!

Most guys my age will have collected at least three or more tire pressure gauges over the years.  Being cheap, most of mine were either free from Big O or Discount Tire or I might have paid a buck for one at Checker.  I’ve had at least a dozen and the four I now have read like the stock market at any given moment during the trading day.  Two of them will read pressures over 90 psi and I tried them out on a very unusual tire that was both over and under inflated at the same time depending on the gauge used.   My inside dually was either over 120 psi or 70 psi.  Not good on either count.

So I have now spent more money on a new digital tire gauge than I have spent on all the others combined in the past 35 years.  It’s the $24.95 Trucker Tire Gauge that will read up to 150 psi and has a nifty led light on one end.  It is well calibrated based on my scientific comparison between it and the tire monitor system on the Caddy.  Only one problem with the new gauge is you can’t ware it in your front shirt pocket.  Turns out my inside dually was only 112 psi – not so bad.  I’m not yet ready to part with my old, wildly inaccurate and cheap gauges.  Maybe a good soaking in Liquid Wrench will get them to work better?
