Tire pressure

[DetJohnO]

I have 2 quality tp gauges which read my tire pressure the same but they differ from the TPS by 3 to 5 psi. Thoughts?

Good day

Are your good quality tire guages both reading the same PSI?

If so, I would go with the 2 quality pressure guages.

You probably already know, but if you have dropped or banged etc any of your guages (same as a torque wrench), you need to get the calibration checked...or more likely, just go get a new quality guage (cheaper and saves time).

Most guages also give you a window as to their accuracy. Usually 1-2 PSI variance is normal.

Have a good one,

Andy

Use a cheap digital gauge, they are much more accurate than the pen style.

3-5 psi is the difference between the tires on the sunny side of the truck and the shady side. TPMS (Tire Pressure Monitoring System - monitoring for trends and extremes, not as a gauge) is really designed to detect issues, like rapid loss of tire pressure or an increase due to heat issues. Once it throws a low pressure alert, you're already more than 20 PSI to low.

The owners manual does state that the TPMS is not to be used as accurate data.
Having said that, mine does seem to match my tire pressure gauges most of the time but definitely not always.

Ya - it's useful for the compare, see if a tire dropped a few for some reason.

Of course, that's if they matched each other based on true tire gauge.

Also useful when seasons and temps are changing, as reminder it's time to increase/decrease.

I ended up with one of these: https://www.amazon.com/dp/B0CDLC8PPR and it matches the TPMS readout.

I have 2 digital gauges and they both say the same, cold in the morning. Yet on first start up, the TPMS is out by 1-2 lbs, no biggy tho! 🛞

Screw the gauges I've tried a few.
I use my Stanley FatMax tire inflator / jump starter. I set the pressure I want and.....

it provides air pressure Nirvana every time.

Do they still make that model?

I don't know. I've never looked for them.
Sam's had them 5-6 years ago for Christmas. I bought 6 for my family.

Had it for well over ten years. Works like new.
Accurate.

TPMS is not accurate. TPMS on my 2025 has always been about 3 psi low from known accurate gauges. Our 2020 escape was 4-5 PSI low with factory TPMS. Bought new tires 6 months ago and installed 3rd party sensors which read 1-2 PSI low.

Topeak - does presta valves too?

I have had this Intercomp for 10+ years 100% accurate all the time! Expensive these days... I paid like $50 bucks or less I think back then.
