Lowering TV tire pressures
For those of you with diesel HD trucks that lower their tire pressures when not towing, what do you set them to? My Ram calls for 60psi front and 80 in the rear. As most know, this gives a pretty h...

How about the inflation table
Not interested in running over inflated. Ride is more harsh and less performance.
Load inflation tables just give the maximum loads for different pressures, they are not recommended pressures.
Vehicle recommended pressures are a compromise between load capability, handling, stopping and ride.
The door jam sticker is for the MAX GAWR of each axle individually. Our 2001 RAM paper work actually had an included document to show inflation for lighter loads.
If you believes in leaving an axle weighing 3200-3400 when empty at 80 PSI, why are you not inflating your fronts to 80 PSI? Oh, wait manufacturer said you only need 60 PSI for that lighter axle load!! Which reminds me, I need to lower my rears to 42 PSI as I will not be towing again for 7 months.
Read my post again, I am not advocating running max pressure all the time, just pointing out that load inflation tables are just that, maximum load ratings at different pressures. If you tailor your pressures for your actual load, you are running your tires at their maximum because that is what those tables mean. They are not recommended pressures, they are the maximum load the tire can handle at that pressure.
