Anyone suggest a optimal tire pressure for best fuel economy for Ram 1500 2012?

If you are looking for fuel economy then max tire pressure is what you want.
I run near max (personal preference) and my Ridge Grapplers wore out on the sides slightly faster than the middle.

hope the OP doesn't factory Load E tires on his truck, running 80 psi on a half ton truck won't do much but make it ride horribly.
Run the inflation pressure listed on the door tag. Too much pressure can cause handling issues.

Tire compounds make the biggest difference for fuel mileage, easy rolling and less resistance. Michelin are about the best for fuel mileage, running door stated air pressure. The factory Goodyear SRA's were good fuel mileage tires, but that was about all they were good for. Anything aggressive in a tire, off road or all terrain as an example, and you certainly will not benefit in getting better fuel mileage.

Use the recommended pressure listed on the door jamb. Higher pressure wears the tires out quicker negating the minuscule gain you’ll get in gas mileage. All the while, sacrificing the smoothness of the ride for nothing.
Lowering your average highway speed by 5mph will do more in terms of increased fuel mileage than anything else. Take a hard look at what “dead weight” you have perpetually riding along and trim the fat, so to speak.
My son complains about his mileage on his “17” w/5.7 Hemi. I’m not listening until he takes out his golf clubs, corn hole boards, portable dog kennel and the +/-100lbs of miscellaneous junk he needlessly carries around under his tonneau cover all the time.

Some tire just won't get good fuel economy Tire weight and tread design. If worried about fuel economy don't run all terrain tires and go a dedicated road tire. Proper inflation is more than just fuel economy, it's about handling, braking and tire wear. You will get different fuel economy per tire pressure yes but tire design is the main culprit.

Every vehicle I have ever owned I always ran 40 psi in the tires regardless what the tires or the stickers said. With the 11 ram I had with the stock 20" goodyear sra tires I got 50k miles out of them at 40 psi and regular rotations intervals.

I have a 16 1500 4WD V-8 with 20” wheels. Run 41 psi all the way around. Get everything the truck can give you. Performance, handling, economy. That is also the spec pressure. You can go just a touch higher in hot weather but the big number is 41 measured cold.

Dentist's recommend 80 psi so they can replace your teeth that rattled out.

I run my 21 Limited (stock tires) at 40. With the air ride it is both comfortable and stable.
Living at 7k ft and on a 90 degree blind curve, I love the all-Season Bridgestone Dueler H/L's. First set of Bridgestone's I have ever owned.
Did not have any slippage last winter -- except when I wanted to. Well there was one slippage on the way up the Mountain to the Ski resort where the road was ice coated and I applied a little to much pedal but nothing out of control.

Best tire pressure is what is on the sticker on the cab door frame. Going lower or higher will negatively impact handling of the truck and make for uneven tire wear.
You have a truck and trucks get poor fuel economy and what you can do is drive your brick slower and make fewer short trips with it. My half ton pickup gets 16 mpg which is about the same as the 3/4 ton diesel pickup it replaced. My Rav4 Prime gets 99 mpg. Guess which vehicle I use to go get groceries?
At least with the gas price gouging struggling companies like ExxonMobile are having record profits with Exxon recording profits of $23 Billion. Good to know our dollars are going to a good cause - corporate greed.

To the OP. See post #2 above and more.
Tire pressure is only a part of many items that will help with fuel economy. Whatever number you choose, check the tire pressure manually, frequently. Checking each tire, frequently, IMO, is better than relying on TPMS only.
Driving habits for any driver of your vehicle matters. There is much discussion on bettering fuel economy in other posts.
All the best, Amigo.

40psi cold at 60 - 70 degrees F. They will increase pressure as temp increase i.e. hot day in the sun or highway. in the winter I will let mine drop to about 37-38 cold.
1psi for every 10 degrees or so.so 40 degree morning i see 38 on dash. Summer sun beating on tire I will see 41 or 42 on startup

Please don't ever go by the pressure that is imprinted on the side of any tire.
The tires on your truck can be mounted on a Ram 3500 that carries a lot more weight legally
Rams Engineers know exactly what your Ram weighs & what it can carry.
The amount that they came up with is the weight on the drivers door sticker or plate
If you can fill your tank & run it only on the highway
you will find approximately what SPEED gives you the best MPG, it will be between 55 & 65 MPH.
I know that i won't be traveling that slow

My recommended tire pressure Is 80psi. I run 68 on the left front. 69 on the right front. 70 on the left rear and 68 on the right rear. That’s what the TPMS says. Everything seems fine and when they wear out I’ll buy another set of tires.

I'm running 55psi as reported by the dash on my 2015 tradesman, and get around 17mpg. Below 50 the tpms complains about low pressure, and I'm not sure if that's the correct number, since the previous owner did a lot of custom work to this truck.
