There is no one size fits all in most things...on this one, maybe OEM or
pure bone stock and not loaded up over GVWR, then follow the door label
If NOT pure bone stock, then all bets off, as it has been re-engineered. Like
over sized tires, different than OEM wheels (dia & bead-bead), or suspension mods, etc
Not all suspensions are the same from OEM to OEM. Why they differ on their door labels
Tire pressure is NOT only to hold/carry weight, but to maintain the tire shape
during all of it's duties
Example of PSI not just to carry weight...either look at or experienced a low
tire pressure. Most will NOT have the rim grounded through the tire, but held
up there with whatever 'low' pressure.
Air it up and it does raise to proper pressure height
Mainly to do with the sidewall characteristics. Of that, mainly for the sidewall
roll over characteristics. On that, rim width just as important if not more than
proper pressure
All tires have a recommended rim width range (bead to bead). That has to do
with both ride quality and sidewall bend back (roll over characteristics).
Most commercial tires (higher class than ST, P and LT) do NOT have very much
sidewall bend back. They carry their load a bit differently than safety beaded
tires do. Also much higher pressures and again, has to do with how they carry
their weight without much bend back
Suspension contributes to sidewall bend back's roll over. Anti-lean bars will
load up the outside tire much more and force it to 'try' and roll over.
If the sidewall is soft, not of high strength and has lots of side wall bend back,
then it will easily roll over.
The transition from going left, then to going right will have a soft side walled
tire roll over all the way from this side, to all the way over to that side.
That is the key to handling and the reaction or performance of a tire.
My recommendation is to follow 'your' TV's door label if your tires/wheels are OEM
If not, then use the chalk or masking tape method to determine the proper PSI
for 'that' loading during that test
