About a week ago,pumped the tires up more than the door sticker called for. Have to belive this helps around town driving. Anyone else tried this?

Front----55#
Rear----65#

The truck is a 06,2500 4x2 CTD-----less than 11k miles(what a beast)

 

Actually, I'm doing the opposite, 65 front and 55 rear.

65# front, 70# rear. I think it helps mileage, tire wear, and safety for towing.

 

I think Nick is right 65 in the front and 70 in the rear if your towing..... but if your not towing I would run the same in the rear as the front or 5 psi lower . Thats what I see works best for my customers at my tire shop.... If you run too much in the rear when not towing it will beat your kidneys to death.. lol

 

Isn't every tire different?

I swear mine call for 80lbs.

 

You shouldn't be looking at the door sticker. On the sidewall of the tire it will tell you what to put them at when loaded. My old tires were 95psi. My new ones are 65psi (I went for a bigger tire this time) but with the same load capacity.

 

I think I went the other way around.

My old tires and rims ( 16" 245's ) if I remember right called for i think it was 65lbs. My new tires and rims ( 17" 265's ) I'm pretty sure call for 80lbs.

 

I run 66psi (easy to read on the gauge I use) all around. I've found it is a good compromise between a soft ride, fuel mileage, and load bearing.

60psi all around gives the truck a really soft ride, but mileage falls 0.5mph or so.

 

High pressure or low pressure, either way is not good for your tires, mileage, wear or ride.

Too high: Rough ride, poor center wear, poor handling because of the small contact patch. Not good.

Too low: Soft squishy ride, poor outer wear, sluggish handling, dangerous at high speeds.

The pressure on the sidewall is just the max load that can be carried at the max pressure. That is not necesarilly the ideal pressure to run at.

You need to figure out the pressure for YOUR tires, on YOUR truck. It takes a little playing, but a good method is using a chalk line. Go to a parking lot, spread a little chalk on the gorund that is wide enough for your tires, then drive through (slowly) and look at the pattern it produces. Too high and it will be narrow; too low and it will be spread out more than the tread.

Or, just look at the wear pattern on the tires and make sure that you are getting full contact with the ground.

For example, my truck, unloaded I run 55 up front and 51.5 in the rear. I'm kinda **** about monitoring my tires, and this gives me a real good wear pattern. Having a good digital tire gauge helps.

 

Running empty I run 55lbs front, 60lbs rear.. hauling my 5th wheel, I run 65lbs front, 80lbs rear (load range E max capacity).
