After viewing the video on comparisons of tire gauges I bought two Etenwolf digital tire gauges, I keep one in the garage for the family vehicles and the second for the race car. I have issues with both in that they frequently fail to properly seal on the valve stem and read the pressure. Not happy, but not worth the shipping charge to return them.

I need a compact, light weight, easy to carry, lighted , (0-40#) gauge. The lighted feature is critical since during the summer months we run many races at night.

Been using a Jegs branded analog gauge. It's about 13-14 years old I believe. Replacing it due to getting inconsistent readings on back to back checks. Varies 1/2 lb or so from itself time to time. Just got a Longacre digital and it's telling me the Jegs is also reading consistently 1.5 lbs lower than Longacre. I'm assuming the new one is accurate, but will be comparing it to friends gauges when I get a chance.

A friend of mine gave me a Intercomp that he used for go carts.

It's the most accurate repeatable gauge I have ever used.

If you have to replace a tire pressure gauge for whatever reason, don't get hung up on what the new gauge reads compared to the old gauge. Certainly do a comparison, but if the car has been working good using whatever the old gauge read, just use the new gauge reading as the new setting. Of course, you can play around with different pressures to see if you can improve, but always use the new reading as the "standard" from the old gauge.

It's rare that you get 2 different gauges to read the same pressure.

Back in the 80's-90's when I raced every weekend, that's pretty much the way I did things. Always tried to keep it simple and not change anything, unless absolutely necessary. Going by memory, I believe I'm at 23 passes on this car and still figuring out what it likes. With the old gauge, 13lbs seemed to work fine. That puts this one at 14.5. Heading to Rockingham tomorrow. Hopefully get 2-3 test runs in tomorrow before weekends race. Knowing their track prep reputation, I'll likely start off at 14.5-15 and adjust it from there. Still working on clutch setup as well, which throws another monkey wrench in there. Thanks..
