How much air in the tires? Need advice... First "real haul"

The tires on my dually don't get too many miles before I have to replace them. We haul thousands of pounds of steel monthly for our business in this truck. I usually replace every other year.

I make all of mine the same... both of the front tires, all 4 duallys, and the spare... been doing it that way since 1970 with my first truck camper.

You'll get a bunch of answers... my way keeps it simple... gets the same tire wear

Do have fun!

My camper is almost double the weight on a dually and I've run 80,000 miles on a set of tires that way.
Now running on a 2nd set of tires with the same.

I agree with Sleepy and I have been doing that with trucks and trailers since the 60's and I don't have tire problems unless I loose track of their age, running tires until they are teenagers isn't a good idea.:)

All great advise. Thank you

First, the right way to do this is to start with the vehicle tire placard. It should be on the drivers door frame. The placard will list the original tire size and the proper pressure for that size.

The second part is: The placard assumes you are towing within the limitations of the truck - so you need to know what Ford said about towing. If you are towing within the limitations, then the placard pressure is applicable (unless there is some additional advice in the owners manual.)

DO NOT use the tire pressure charts by themselves. Those are NOT recommendations. They are minimums.

DO NOT use the maximum listed on the sidewall (unless that is what the placard says to use.) The tire manufacturer has no idea what the load is going to be on the tire, so the maximum pressure on the sidewall is just that - a maximum, not a recommendation.

In all likelihood, your truck will call for a pressure less than the maximum on the front. Please be aware that Ford tested this truck at those pressures and unless you are willing to conduct your own tests, I think it would be wise to follow their specification.

Search for rv tire inflation charts to know how much air is required for a given weight. There should also be tire inflation recommendations on the sticker that has the gvwr.

In my load range E winter 16" tires, I run the required 80. When I have my summer 19.5 tires, I run the required 110. Best for tire, best for driving. Sleepy is right. Keep what the mfgr says when hauling a load, and you will be fine.

Load E rated tire, I put 80 psi in the rear unless I am "off-road or sand". In those conditions the traveling speed is greatly reduced though.

Also suggest you weigh your rig fully loaded so you have an informed decision on how much weight the tires are really carrying.

Damn, Sleepy could close this thread! I agree, so many reasons to use max pressure for heat,capacity, sway control,all related to tire safety and life,( incuding yours). If you see the tires wear in the middle more than the outside edges, lower the pressure.
Seriously, with that kind of weight we carry, the max is usually the best.
My camper dry rates at 2200 lbs. The scales put me at 3000lbs. You really do have some weight on there,,happy travels!!!!!!
