I don’t know how I missed that thread mopar referenced, but anyway.
There is one issue with the Longacre Racing brand of gauges I recommended, and it usually prompts this response, in the form of a ?…
“Who in half their right mind would pay more than 50 bucks for something to check tire pressure?”
Well, I for one consider tire pressure to be critical in vehicle performance. It’s the part that touches whatever you’re driving on*
*Disclaimer: This statement does not make me better or smarter in this regard than anyone else.
As far as are things being made better than they were 50-70 years ago is concerned, well, I had asked around town if any garages still had one of these bolted to a corner of their workbench, by which I could check how really accurate these Longacres, and other gauges I owned, were:
Nope.
So there must be some reason why car repair places don’t have one of those any more.
Gut instinct would tell me that the tire gauges of the last twenty years, any way, have improved accuracy to the point where a ‘master gauge’ is not necessary, outside of scientific or manufacturing facilities.
Now you guys know I’m a fan of the time-travel science fiction genre. Suppose I’d gone back to Chuck Berry Land, or Presleyville, with the Longacre Racing Deluxe model gauge in my backback.
#1. I’d be brought ‘downtown’ to explain this device I’m carrying.
#2. Every repair shop in town would be asking me to verify the accuracy of the pressure gauges in use back then!
Back to the Future.. whew!
The point is, some products, such as tire gauges, have improved in build quality and accuracy, regardless of price. I just wanted to be sure the gauge I use returns repeated, accurate results, every time.
And that is probably a good reason the master gauge I posted the image to is no longer necessary in every car service bay or garage.
