how do you reset low pressure air light?

I have and 05 armada and my girlfriend had a blow out in it. I put the spare on and ever since the low pressure light won't turn off? I bought a new tire and put the original rim back on and it still won't turn off. I've checked the air pressure in all the tires and they are all equal and good. Any suggestions? Thanks....

Driving a short distance with the correct air pressure will shut the light off. I think the manual states that the TPMS will activate when the pressure in a given tire reaches 29lbs. I would add a few more lbs. into each tire to offset any variance in the tool that you are using to measure tire pressure.

I use a "pen" type gauge and it's around 10% off on the low side compared to a good dig. gauge.

your suspension might need some tuning up.. perhaps the springs in the front or the leaves in the rear. that happened to me
