Tire Pressure Indicator Light

i aired up to recommended spec (including the spare) and drove around for like a week and it didn't go off... so i filled them up 3psi more each and drove about 4 miles, then i went to the dealer and they checked with their gauge (in case mine was off) and they verified that all 5 tires were within spec, so he hit the button and it didn't go off so we started talking about possible problems and while we were talking it went off. So IDK... maybe changed in the newer year models?

 

You can flip it over with no problem.

Correct...
except I think it is set at 29psi (or whatever is listed on the door panel of your truck for the stock set up). The TPMS comes on with a drop of 25% from whatever psi it is set for. So if 29psi it comes on around 22psi.

But very good info posted there ^^^..

Set all your tires at the PSI you want to run, for stock tires/rims setup the suggest psi is on the door panel, then push the button and it will be set at the psi you chose.
You can choose a different psi based on your preference, tire changes etc and reset the tpms for whatever psi you choose. Just do not set it too low.
