Some of you may remember the payload capacity thread, especially the low payload capacity for some of the '09 Platinums. A search can find the thread on payload.

What made me revisit the payload capacity was my registration slip. Something is missing or wrong. Look at the pictures below for the edited pics of registration and tire capacity.

The empty weight of the truck is 5,408 lbs per registration. Given the registration and title were issued from the manufacturer's statement of origin (birth certificate for vehicles), the empty weight is certified by Ford.

GVWR is 7,200 lbs. Deduct 5,408 empty weight, leaving 1,792 lbs for payload capacity (includes passengers, fuel, and cargo). But the tire capacity sticker shows maximum payload of 1,153 lbs, 639 lbs less than expected.

Did Ford mistakenly under rate the payload capacity on the tire pressure sticker? The difference of 639 lbs is too large to be ignored.

 

Just a guess here since I'm not familiar with the low-profile 275/55-20s yer runnin', but I'd guess that if you look at the max load rating of those tires as printed on the sidewalls, you'll see that the tires are the limiting factor for loading your truck, not the design. If you actually plan on using your truck to haul at or near the rated weight limit, you might want to pick up a set of junkyard wheels/tires in either the 17" or 18" size.

 

I could be wrong here but I think the load rating is lowered because of the "P" rated low profile (55 series) tires installed on the truck from the factory.

Too slow again........... LOL

 

Big Ole Truck - not sure about your question. What part of Fla - just curious....

 

Just checked the stamping on the tire (20" Pirellis). It says max. load of 2403 lbs at maximum tire pressure of 44 psi. So the tires are good for the load.

 

Panama City...NW FL

 

Just remember that the load rating on the tire is at maximum tire pressure (44 psi) and not the recommended pressure (35 psi) which the Ford rating is based on.

 

(While I know this Thread is OLD (01/2010), but in case someone finds it perhaps what I have added here may offer some more insight on the Payload questions)

Also from FL, and with an 09 Platinum - my reg NET WT is listed as 5408, same as yours. My GVW is listed as only 5999.

The 5408 listed is a 'Curb Weight' - BASE Truck NO OPTIONS So the weight of a F150 Screw 5.5 bed Truck. The PAYLAOD (Sticker - read below) is based on the REAL weight of the Truck. I weighed mine see below:

The Sticker on the Driver's door (Tread Act Sticker) is the payload rating of YOUR Truck based on the Options. The Rating 1500+ lbs listed in the sales Literature is the MAX POSSIBLE Payload for that Body style (a Base version of the truck - no options)

I have a 2009 F150 Platinum SCREW 4x4 - the Tread Act Sticker indicates 1096 LBS. The Trucks GVWR is 7200 lbs (On the Vin Sticker on the door) Well here's the reality - My Truck weighs with ONLY me in it (190) and a full Tank of fuel 6320 LBS . So that leaves me with 880 lbs [GVWR (7200) - 6320] of Payload (aditional Passengers, cargo and yes tongue weight) in the Truck .

In defense fo Ford, this Advertised Payload is done the Same for all Manfactures (GM, Dodge, Toyota). So if you want to compare Payloads, look at the Tread Act sticker on each vehicle .

So while I believe MY Truck can handle more that me and 880 lbs of Payload/Cargo, IF I WANT TO BE LEGAL, my limit is 880 lbs. with me in the Truck.
I also initially thought the Yellow Tread Act Sticker was telling me that my Pirelli tires were what was lowering my payload, but the Pirelli's have a Rating of over 2403# per tire. While the yellow stick is the Tread Act Sticker and seems to be connected to the Tires, due the math on my Truck and you see that Tread Act Number is based on the Truck's GVWR (7200) minus the actual Trucks weight

Truck weight minus Me (190) (6320-190=6130)

7200 - 6130 (Truck w/o me in it ) = 1070 for payload

and the sticker says 1096 (Okay 26 lbs different - well that would account for the SOFT Tonneau I have on the 5.5 box.

So the Pirelli's aren't the determining factor - it is just simple math the Trucks GVWR (7200 for My F150) minus the ACTUAL Weight of my Truck - what is left is your 'legal' payload and posted on the sticker on the D Door.

The 275/55R20's Have a 111T Rating that's a 2403 lb weight rating and 118 mph speed rating.

So with 4 Pirelli's the Truck should handle a load of 9612 lbs - way more than the Trucks 7200# GVWR -

 

I'm interested in the load limits too
My P255 70/R17 tires are rated @2337 x4 = 9348 lbs
My GVW is listed as 6950lbs on the door
Listed Max: Front axle 3750, back 3800 load =7550 lbs
Max cargo + people listed as 1250 lbs

My registration does not list a weight - not commercial
I do have an Inspection report (Ford dealer) that lists GVWR as 8500 lbs
8500- 6950 = 1550 lbs
So no wonder people get confused

My truck is a 6 passenger
Say each weighs 180 lbs = 1080 lbs
so only a 170 lbs after that can be loaded
...now add in the tongue weight if pulling a trailer
But I think everyone has seen 6 people in a truck & another 10 in the bed
...not on the highway..so thats a load of almost 3000 lbs
Now is Ford/Mfgs simply under rating the trucks so that anyone that goes over voids their warranty ?

I know I have had 3000 lbs in my truck
Miscalulated the weight

 

This all has been driving me nutso as well...

Sadly, in 09, the GVWR is listed as 7200, with the front axel at 3900 and rear at 4000. In 2010, same frame, tires, axel components, and with the same 3.73 diff, the GVWR went to 7600+, with the exact same front and rear ratings as they were in 2009. (scratches head)

I did find some literature once that stated the gawr (rear) rating was the lowest rating of i) the tires, ii) the springs, iii) the axel. Tires are 4800 (together), springs are 5000 IIRC, so it must be the axel components that limits the rear to 4800.

FL150 - I assume that this site is yours? Nicely done.
