Rob,

This is great torque. But it is on premium fuel where the HD engines from GM and Ford are certified on regular grade fuel. The HD engines do not use AFM/DFM or stop start so they are simple designs made for durability.

Moving on.

In the immortal words of Keanu Reeves, Whoa......

I could never wrap my head around why the manual for my truck build code said my Payload was 1680, and my Door sticker said 1380. This is the explanation!

So if you don't mind educating a newbie(ish). Is this due to the Stock tires (which I don't even have anymore)? IE, is there some third number I should know. (I don't know what tires are on it right now, I bought it used, and the dealer put some newer tires on it. I'll have to wait for daylight to see what they have)

Hi Mike,

I am not sure what you mean by "the manual for my truck build code" but any document or label that includes the VIN of your vehicle should agree on the numbers. Advertising information usually quotes the largest payload possible with the lowest option content, lightest vehicle build possible.

Once this "payload" number is determined by the manufacturer and documented on the label, it can never be changed. This documentation will reference the original tire specs and to maintain that payload, tires of at least this capacity would be required. Anything added to the vehicle after it leaves the factory (bed liner, tonneau cover, running boards, etc) will subtract from this number but the weight of these things can only be determined by subtracting the actual weight of the vehicle from the GVWR documented on the door label.

Cate&Rob ,
The way Toyota does it, The manual the comes with my truck has an appendix that lists all the specifications for the truck. Since the manual is generic, it wouldn't do it by VIN. Instead they have a Truck Build Code. Think of it as a Simplified VIN that contains all the options the truck was built with.

Mine is USK56L-CRTSKA. When I look this code up, it says the Payload of the truck is 1680 (or close to this, I don't have this number burned in my memory since I always went with LOWEST number I found).

But the Yellow Sticker talking about TIRES and LOADING information with the tire pressures says the payload is 1380. (I actually have third yellow sticker that says subtract 30 pounds due to installed accessories, so it's really 1350).

I never could understand how the manual could have 1680, but the truck sticker says 1380. Now I understand that the truck sticker is also considering the specific tires that the truck left the factory with, while the manual code is probably independant of Tires.

Short answer, ALWAY look on the physical truck, and trust the book as far as you can throw the truck.
