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...

I’ve currently set 55 front and 60 rear which is a much smoother ride but I’m wondering about the effects. Tire wear? Controllability?
Will lowering the fronts cause steering issues? Since all the weight is up front with the diesel should I lower them at all? In theory, with all the weight up front and little in the rear I should be able to lower the rears to less than the fronts. Any problem with that?
OP has a 2500 Ram with the Cummins and seeks help with unloaded pressures for that truck.
It would help is he and others that are interested in helping him need to add his/their tires size/load range.
Depending on what size the OP tires are 55 psi may or may not work the best. I would think 55 psi with a heavy diesel sitting on them (especially 17" tires) will be under pressured causing premature wear issues/hotter operating temps.....but sure would ride good.
60 psi in the rear tire on a 2500 truck ? Regarles of size IMO 45 psi would be a good place to start. Always moniter tire wear patterns. It a good indicator of your tires pressure needs.
