I think that is close as you going to get it!
Its a user perference.
Some like there tires inflated more than others. But if you go over then the center of the tires start to wear quickly. So I think the chalk idea is a good way to fine out. Or take your truck to a scale and wiegh it! I think there is a pressure to weigh chart in the owner manuals in the truck!
Basically no one is taking in calc. that so people carry more stuff / junk in there trucks than others!
If you go under inflated you will have a blow out. Too much rubber flexing cuase it to heat up and blow out!
I would rather be over inflated than under!

Chas,
I wonder if 55 is a little low on our trucks? BTW, how'd the 2WD do in the storm last weekend?

The 2WD is a summer toy, it never moved in the storm. Used my Geo Metro (3cyl)
I'm in Richmond and work in South Portland, the Geo was the answer to the fuel prices

What about low Pressure?
My Factory shop manual shows with OEM 265/75R16 w/diesel - empty 45psi front 40 rear. I have always ran more than this but with the addition of my KORE system I lowered the pressure. Not as low as KORE recomends. Did not help the ride much.
From KORE:
Your racing shock absorbers are designed for use with realistic off-road tire pressures. For trucks carrying loads under 1000 lbs we recommend cold pressures of 30 psi in front and 30 in the rear. Due to their thick sidewall construction, heavy duty off-road tires such as the “Goodyear Wrangler MTR” or the “Toyo Mud Terrain” require even less pressure to work properly. Try to experiment to find the tire pressures that work best for you. If you are running pressures above 40 psi to attain longer tire life or better gas mileage, please be aware that your suspension will not function optimally. Higher tire pressures may only increase tire life and gas mileage by 3-5%. Lowering your tire pressures will permit your tires to absorb initial impacts more efficiently, transmit the correct secondary impact velocity to the springs and shocks, provide better resistance to cuts and abrasions and increase your traction – especially during braking. At low speeds, due to increased rolling resistance, your steering will feel slower, but at high speeds you will perceive greater steering precision due to better traction. When you are towing or carrying heavy loads, use appropriately higher tire pressures, then air down when empty.

65 in front ,40 in rear X 4. ain't no load in th back ,don't need all that air. I just backed the pressure till the fuel milage started suffering, centers were wearin too fast. at $130 a pop I need all the tread i can save. thinkin bout taking th training wheels off, can't stand the way it looks tho with just two outside tires.

Detailed Guide with truck.
Am I the only one who has one of these?? My 03 came with a VERY extensive guide that took into consideration, truck model, engine/trans combo, different loads, plow/no plow, speed being traveled, as well as tire size and "D" or "E" range. Its a big fold out job that takes a little while to work through be cause of all the variables. But it seemed to be the best attempt at giving owners the right information I've ever seen. I think that every car sold should have one!
If anyone is interested more info from this sheet, let me know.

There's an informational manuals under all that junk in the glovebox?
Who-da thunk-it?
Actually all I've used mine for is to figure out how to set the clock.
Now my factory service manual,.....that's a whole different ballgame.

The tire supplement manual is something that started getting added in 2002 model year. Partly due to the Ford Explorer and Firestone Issues. NHTSA kinda requires it now. It is suggested pressures under certain conditions.

That would be nice to have, where would I get one?
BTW: I was thinking about jumping up a tire size, next time around, to 285's. Can I go this large on my 2WD?
Sorry, don't mean to hijack the thread!

I bet the supplement is available from the dealer. It has to have a dealer part number if it was delivered with the truck. Just ask the parts counter. I will look at mine to see if there is any number to reference.

I took out the tread depth guage and checked my tire wear across the face of the tire and found that I'm almost flat faced. +/- 1/16 Inch difference.. So for you guy & gals running a LWB 2500 Truck with a shell here is a good startingt place.
