After getting new tires I noticed my TPMS being off.
all 4 are around 5 lbs high.
I have checked with 3 different gauges.

can they be reset?

 

Usually the system will recalibrate by itself same as a tire changes pressure vs temperature as long as you set the pressure you want cold, as a system reference.
I set my pressure after the vehicle has set all night to be sure all wheels are the same temperature.
Otherwise you can't just set pressure anytime and expect the best true tracking, not even from the tire shop.
I have watched my system operation while driving over the last 2 years and learned a lot.
Tire pressure changes are 95% due to road surface temperature changes as you drive. The rest is tire squirm/loading and how hard the vehicle is driven.
You have to set the reference pressure first or the reading don't reflect the true pressure results.
Good luck.

 

Are you sure? Are you certain you are not still seeing the pressures from your old tires?

Go let another 5 PSI out of a tire and see what happens to the display. I don't think your truck has seen the new sensors yet. Or, you don't have sensors or compatible sensors in the new tires.

 

When did you get new tires and how far have you driven since?

 

TPMS sensors cannot be calibrated. Try not to be bothered by the reading being a few pounds different than what your hand gauge reads. No doubt the system will still alert you when/if a tire has gotten low on pressure. Rest assured there is plenty of leeway that 4psi isn’t going to make or break you.

I think I typed that paragraph to myself. Lol. I’m acting OCD over this very thing. I have a “certified accurate” digital inflation tool at my shop and I recently discovered on my Acura TLX that it’s consistently off by 3psi and it’s driving me crazy.

 

Please consider the following carefully, re read it and think about it.
A. It does not really mean anything to have a 'fully accurate' pressure meter.
B. If a Digital meter that will read to the nearest half pound >>regardless of absolute accuracy<< is used to set the tire pressure, at least there is a reference to begin from >regardless of absolute accuracy<.
C. A pressure meter does not have to be absolutely accurate if the same meter is used on all wheels. How many times must this be said?
D. If the TPM sensors are good, no low battery or other fault etc, the pressure set will be within reason even with a noncalibrated meter.
E. The stock sensors will not register a half pound resolution a good Digital gauge can offer. Accurate or not, your already closer.
F. Setting with a decent gauge offers a (reasonable reference) to see what all the sensors are doing after setting your reference when all wheels are cold after setting overnight.
G. On my 4 year old 2018, it showed ONE sensor to be 1 to 2 pounds different than the other three regardless of what corner of the truck that wheel was put. This was verified by the same pressure meter used to set all to begin with and re-measured many times on a consistent basis.
H. You see that gauge accuracy is not all that important with sensors that cannot resolve less than one PSI.
I The lowest pressure before Dash alarm was found to be about system indicated 28 PSI.
J. I had to replace one tire due to picking up a small bolt while out on a high-speed highway. The TPMS regained that sensor pressure reading by itself with no help after just 30 minutes' drive time.
K. If one pays attention. a decent Digital meter and reference setting done, it makes little difference on absolute gauge accuracy and not try to pin thinking on absolute accuracy in a system that normally >wanders< in pressure, while driving. All wheels will not move pressure the same at any time or driving conditions.
The Digital gauge I use is that familiar GREEN color offering in the stores.
The TPMS are more of an accuracy issue than the Gauge used. Trust the gauge over the TPMS reading.

 

It’s not my TPMS reading that is driving me crazy, it’s my tool that’s driving me crazy. I’ve verified on multiple cars now that it’s consistently off by 3psi. I paid nearly $200 for a “ansi standard of .1psi resolution and +/-1psi of accuracy”.

You are correct that close enough is good enough. But trust me, there are plenty of customers tuned into that damn reading on their dash and plenty that will challenge you if it’s not the reading they want. Lol.

 

amen to that. I bought a relatively cheap inflated/gauge from a big box store and in 6 months it was off 10 psi and wouldn’t zero out. Into the trash it went. Use my nice pencil gauge now.
hear Jaco is good.

 

from Ford
Locate the TPMS reset button (usually beneath or near the steering wheel), and hold it until the light on the dashboard blinks three times. Release the button, start the ignition, and the light should be off. Add air to all tires (including the spare tire) to 3 PSI over the recommended amount.

 

At my old job we got our gauges (aircraft) calibrated all the time....read within 1 psi of my digital PSI gauge i had for my harley (cost a pretty penny), read within 1 psi of my cheap husky digital gauge, and matches the TPMS readings in my truck lol
