TPMS set point change
I am buying a 2011 GMC Sierra 2500 Denali 4x4 LML this week. It has the stock Badyear 265/60/20s on it. I am going to be putting on some 305/55/20s in the next 2-3 weeks. I want to get the dealer to lower the TPMS set points. The new tires I am going with are load E, 65PSI max. What should I have the TPMS set points changed to?
Thanks for the advice!

My buddy took his T2 home one day and reprogrammed mine to 35psi for me! Charged me $20. Well worth it IMO as I only run 42 psi in my tires!

I had the dealer set mine to 55 when I changed tires. I do change my pressure based on whether I'm towing or not and haven't seen a tire light yet.

I ask, because I think I have a 50psi set point and the light comes on at 45 and goes off at 55. Since I run 50 psi, I wish I had a lower 40 or 45 set point, my light comes on when the tires are cold and goes off while driving.
To the OP I would think you want either a 45 or 50psi set point or 5-10 psi lower then what you are going to drive around at unloaded.

How do you lower the range? My dealership said they could not do it. I have 305/55/20 Terra Grapplers and I want to run about 40-45 psi without the light coming on.

The over under is defendant on how it was calibrated from factory, based in wheel size and tire rating. If the dealer won't adjust find one that will or someone with a tech 2. It's a 5 minute deal.
