    My question is related to the TPMS system and airing down tires when off -roading. I have a 2019 Tundra, was wondering if any damage or long term effects will cause problems with the TPMS system when off roading for the weekend and running much lower pressures during that time. Airing down is something I have not done yet, but plan on doing for future trips based on all of the positive information available for this topic. Any comments would be greatly appreciated.

    Been airing down for years... No issues. You just have the nannies barking at you until you air back up .

    It will just be a low pressure light on the dash. You can just reset that with the TPMS button by you’re right knee. And then reset it again once you’ve filled back up to the normal air pressure’s. All it is, is a parameter. If it drops below a certain psi after you set it,the light comes on.

    I’d have to look in my manual, but I’m pretty sure you turn the ignition off, hold that button down and turn the ignition back on while holding it for a certain amount of time. There may be a prompt on the dash, I can’t remember exactly.

    Thank you for all of the feedback, I will definitely check on the reset to understand how that works. I didn't think it would be a problem, however there are instances when the wife is driving on some stretches, and I didn't want her freaking once she saw the TPMS light, I can forewarn her and let her know it's nothing to be concerned about.

    Just me shit posting. But don’t push the button.

    If your TPMS is working great, and you air down, a light is expected. But if you reset or recalibrate the TPMS cause you are off-road, and obviously aired down...why the fuck would you calibrate your TPMS as low pressure as standard?

    In case they get even lower.:notsure: Or if you just can’t stand warning lights. I personally never reset it.

    Resetting the TPMS at the lower pressure to turn the light off - In case you get an actual flat you will get a warning. If the light stays on all the time and you lose more pressure you might lose a tire also. So it does make some sense to do it.
