It’s true !
This one very old aluminum tire pressure gauge has amazingly held its exact accuracy over 40 years!
Although dented don’t let the gauges outside appearance cast any doubts. Always stored precariously in either a wrapped tool kit, empty beer can, or top drawer of the top box, this precision tool never ever disappoints. That satisfying “psshh” sound as the gauge scale moves rapidly to the exact true reading and stops right there ! Not 1lb psi higher or lower ?
This very gauge has been precisely used to set tire pressures since about 1977 on : DT175, 2CR125’s, MR175, DR400, XS650SP, XJ650RJ, FJ1200, YZ250, CJ5, and Many XS650’s !!
Although other less accurate tire pressures gauges come and go… the Best One of all time still provides the satisfaction of knowing it’s true accuracy is within the undesquingable (that’s a word) feel of exactness, even though the 60 year old arms feel different on a bicycle pump nowadays.
Just now, set these tires to 40.0 psi for winter storage in the cold garage.
But temperature or altitude does not matter with this particular tire pressure gauge. It’s been accurate in conditions ranging from the high altitude Montana mountain passes to the sea level Laguna Seca road course.
