2015 wheels on to 2011 sierra - Re-learn TPMS

[Gooseslayer717]

I purchased 2015 sierra 1500 rims and tires, i assumed that i would be able to just relearn them using the delfation technique but that did not work.

I purchased a Re-learn tool from amazon and it works on my current wheels, but will not work when i put the new tires next to truck and use it.

Do i need to re-learn the TPMS to the truck with the new tires from a dealer or is there something i am missing.

I read about "Waking up" the tpms in the tires but i would prefer to have them working before taking the time to install them, it not work, then have to reinstall old ones.

Thank You

I would say that you do not have sensors in the wheels that you bought. The sensors used in the '11 and '15 are the same and the air out method should have worked if the sensors were there. The air out method and the re-learn tool basically "wake up" the sensor on command while you have the truck in relearn mode.
