Rcdr Selected Tire Type

[carlom]

I am referring to the remote control door lock reciever module set-up: selected tire type on a 2008 sierra k-1500. What is the psi range within each load range (c,d,e) before a low or a high warning is triggered? I now have the original 265-70-17 load range standard tires running at 40psi which sometimes triggers a pressure warning. I will be putting 265-70-17 load range d on the truck and have dealer reset selected tire type to d. I will run those tires at 55psi. What is the psi range of tire type d in the module set-up? Two different dealers service managers do not know.

Thank you.
