Light load settings

[11dodge]

Is there a trick to the light load setting button after putting 37" tires on? Is throwing off my psi reading on dash monitor on 2011 cummins. Pushed it to take "off" light load and still blinks......tire shop double checked all tires are at same psi.....tricks? Help? Thanks

I went up one size on my 13, the light load no longer works, it flashes then defaults to the heavy. I am able to run 65psi front, and 72 rear without the idiot light coming on.

Good luck.

Ya I read where you have to push it twice then drive over 25 to let it reset itself which it did until it came to turn off the truck and turn it back on. Guessing I'm just going to have to run around and adjust tires to dash....
