That's what I would run and watch the wear on the rears.

I've owned all three vehicles and had great results with these settings:

for the V10 (18" or 19") 41/43

for the V8 (18" or 19") 41/ 43

for the V6 (17") 40/42

for the V6 (18" or 19") 41/43

Anything lower than 41 psi on the 18" wheels have worn the outer treads quicker. I add 3 psi to the rear when towing over 1500 lbs.
