I've got E4 rated Coopers. They handle 2,833 pounds at 50psi. Ford threw almost everything at my truck. It's got the Platinum goodies. Max Tow with the large mirrors and brake control, test locking diff, Sony nav system, sun roof, skid plates, FX4 springs. Bed extender, and the previous owner installed a gooseneck hitch in the bed since I'm in horse country here in Colorado. I've had about 1,000 pounds in it for a cross country trip, and it didn't seem to sag at all, but I know that wasn't a real test. I imagine I'll use a trailer to haul any large loads. I can say that this thing has tons more power than my 2001 Dodge Ram 1500 with 5.9 Magnum v8. With five people plus luggage, the F150 chugged right over the pass on I 70 west of Denver at 65 to 70mph. I had to slow down when i reached the tunnel. In 1991, my brand new Isuzu Trooper couldn't stay in 3rd gear or go more than 30 mph over that same pass. Huge difference. Of course, that's unrelated to payload rating.

The E4 doesnt mean its e rated. E4 is a stamp saying it meets ECE regulations. The stock tires that came on the truck were rated for 2400 each so the tires are not technically the limiting factor as they hold more than the Axle weight ratings, which themselves are higher than the GVWR.

Mizedog, you mentioned the spare in your truck is a Load range C. Trucks new from dealers come with the same tires including spare.The Coopers must be replacements,right? No matter what tires you put on [ E or even D is better than C ] you have to follow the limits what the sticker on the factory hitch [ you have to crawl under the rear and look up ] allows. Mine said the TW is 1150 lbs. What it means is if you have a 1000# trailer tongue weight, my TT's is 960 lbs, adding the drawbars, hitch/ball/swaybar/s you're right at the max allowed.The tire's max psi is 40 on the yellow door sticker but on the tire itself it's recommended 50PSI when cold for maximium trailering weights. Obviously Ford installs the C rated tires for comfort. Most people use these 1/2 tons for grocery getting and like to have a plush ride, LOL.
The most important number to be legal is the GCVWR for these 1/2 tons. It's only the two of us traveling, so I'll never exceed the max 1605 payload. If one wants more payload, a 3/4 ton should be on their shopping list!

OK, I've found a Black 2104 FX4 with all the bells and whistles. Ecoboost, 20's, leather, nav, Max Tow, roof, but it has the 6.5" box which I don't like. I'll have to make up my mind whether or not this is a deal breaker. When running the VIN I notice it lists "With Load Leveling Trailer Towing" as one of the options. Can anyone tell me what this is? I will be towing with this rig and don't want the rear dragging on the ground and the nose in the air. It'll look like a dog dragging it's *ss on the carpet. Not pretty! Do these trucks have an issue with a saggy behind and if so what is the best "affordable" option to correct this?

I know what you're saying, I like the 5.5 box myself. If I want to do home renos I'd have chosen a long box. I use the truck towing my boat or travel trailer. It won't sag withthe right setup. Obviously, towing the TT with 960 pounds tongue weight, must use WDH no matter what.My boat with twin engines weighs more [ 8300 lbs ] than the unloaded travel trailer but the boat trailer has different weight distribution characteristics with long frame with less toungue weight,so I don't use a WDH drawbar setup on that.
If you zoom in the second picture, you'll see I removed the drawbar to see if the truck would sag under the 960lbs tongue weight. If I remember correctly, the airbags only had 20psi in them. I only use the airbags for stabilizing the truck from side to side rocking even when not towing. I recommend to install airbags for sure.

Turbo, I have to respectively disagree with your statement "Trucks new from dealers come with the same tires including spare."

Not with the OEM 20" wheels.. As you can see below, they list the spare tire as LT275/65/18 and it's max psi @ 50. This spare is also the Goodyear Wrangler. The OEM 20's on my truck were the Bridgestone Revos or something like that. I bought the truck brand new off the lot too.



Nice TT and boat you got there.. Is the car under the cover a Vette by any chance??

I don't think those are tires Ford put on your truck and they are not E rated. They appear to be XLs at 50 PSI, pretty much a C rated equivalent.

Edit: just saw there was another page with this already stated. Sorry.

Yes, I can tell you that "With Load Leveling Trailer Towing"=Max Tow Package in ETIS English.

No, not a Vette, albeit I like them too.

Your truck only has 1531 lbs of payload because its a bloated whale with all/almost all of the options. Mine is the same way, 4x4 Lariat 502a Supercrew Max-tow and only 1539 lbs of payload. Had you bought a no option XL 2x4 it would have been much higher.
Wow, I have a hard time believing that the options add up to 400 pounds extra. But, that's what the sticker indicates. So, if my family weighs 700 pounds (I know, I'm not small), then I can only handle a tounge weight of about 800 pounds, or less, depending on how much is in the bed, and how much the gooseneck hitch weighs. Sounds like I would be stuck with a pretty small travel trailer to me. :(
I checked Cooper's specs and they describe the load range as "XL", rather than "STD" (who knows what that means, probably a light truck petri thing). On the up side, I was thinking of a set of BF Goodrich All Terrain ko2s, load range D. With my wimpy payload, etc. They sound like they would be enough.
Where are you getting the numbers you posted? Your truck scaled at 5700 with a full tank of gas? 1900 looks more like a marketing maximum advertised payload for 2012 than a sticker number? What limitation are you asking about?

The payload sticker number is a calculated value that subtracts from GVWR. It is the what is left after your truck's curb weight based and factory options are subtracted. Each option has an assigned weight value. The chart is on here somewhere.

That payload looks about right for a non max tow. It looks like it came with p rated tires from factory. What model and packages on your truck? All the whistles and bells start to chip away at your pay load

Dog, tires alone don't make up for the payload... ;)

You can put load range G's on it and it'll still only have a #4050 axle rating and whatever payload rating you have..

Now, going over either of those won't make your truck implode the moment you hit the road, but it's up to you to determine what 'rating' you wish to follow..

Those XL rated tires exceed your trucks rear axle rating by some #1600 pounds.

Anyway, you lose a lot with the CC option alone.. And yes, all those other options add up pretty fast.

Wait till you start to load up your travel trailer! You don't think all those "little things" add up, but they do! Really fast too... I maxed out the GVWR and a couple of extra lbs over on my TT within a couple of years of ownership and some 'upgrades' to the trailer..

Good luck!

If you have the 36 gallon fuel tank option that is 100 lbs off the payload right there. Running boards are pretty heavy. 20" wheels add like 50 lbs or something. Skid plates if you have the FX4 pacakge? factory Spray in bed linear?

Those are all subtracted from the advertised payload because they are talking about a no option XL truck which will have none of those things.

Yep, I have all of those. Plus the locking diff, bed extender, and tailgate ladder, and tonneau cover. For daily needs, this truck is a joy.

So I don't really tow a lot. Maybe a uhaul trailer here and there. Does this mean my max tow is #10500? Excuse my lack of knowledge. Only thing I used in the past to tow was an old cummins with a gooseneck and we were hauling hay and never worried about the weight. Now I'm looking at getting a camper and I'd rather not "*******" guess it haha.

Your hitch receiver is rated at 10500 with a weight distribution hitch. Your truck is not likely to be rated that high.

I have the 4x4 lariat with the super crew cab. 5.5 bed.

Is it springs that determine a lot of what the truck is rated for? Or gearing and axels play more of the major role?

Thanks for the education.

It's the engine and gearing plus options A lariat / platinum have really low payload and aren't really optioned well for towing at the max.

In most cases everyone runs out of payload and rear axle load rating before they get anywhere near the 10,500 receiver rating.
