Increased towing capacity possible?

The Tundra is a 2019 long bed. I want to tow a 14,000-pound rated flatbed trailer. I was unable to find the Trailer Weight Rating (TWR) anywhere on the truck, in the user manual, or using Toyota's detailed spec sheet for the VIN (5TFCY5F16KX02XXXX). I have written Toyota to request that information.

From reading the Owner's Manual, it looks like the highest TWR for this year model in any trim form is 10,100 pounds. I do not know if adding aftermarket suspension parts, like air springs, can legally increase the TWR. I do want to be legal and safe.

Any information or advice you are willing to offer will be appreciated.

Thanks

 

You cannot add load carrying capacity in the eyes of the DOT. All modifications do is improve how the truck handles the loads for which it was rated. I have sumo springs to reduce sag, but they do not increase my ~1,300 payload. The same goes for towing.

If you really need to pull a 14,000# trailer, you need something more capable than any 1/2 ton on the market.

13% of 14,000# is 1,800#. No half ton is going to handle that payload. Thus the term "half ton"

 

Thanks Retroboy,

That's what I was coming to believe too. I am not knowledgable about trailer towing and thought there might be a way to make the existing truck work. Maybe someone has mods that will work.

 

Yes it's totally possible! Go down to either a Ford, Ram, or Chevy dealership and trade the Tundra in on one-ton (or greater) truck built for towing that amount of weight.

 

It's not possible.

You can do it but it will be a strain on your vehicle and not safe for you or anyone else on the road. Despite what people who come and and state the forum tow police should be ignored.

Don't do it. Buy a bigger truck or smaller trailer.

 

So just out of curiosity...... What do you plan on hauling on the trailer? Yes it is rated for 14k pounds but maybe you are only pulling a 1,200 lb. zero turn on it.....

 

Think space shuttle!

 

Yeah for a stock truck I'd think 6-7k would be about the max. for the best results. However, size is also a big factor once the wind blows. As for the shuttle, only a joke! That said, her post only says trailer, don't see anything about it being loaded.

 

You quite don't understand do you? Truck is too small...get a bigger truck...That is the only way to do it safely....But I'm sure Billy Bob has a way, go talk to him....

 

Well, folks, I appreciate some of the responses.
I don't like the sarcasm and do not know what I wrote to prompt it.
I wrote that I do want to be legal and safe.
My intent was to normally move much lighter loads.
I have a TLB that weighs over 10,000 pounds that I may need to move.
A smaller, earlier Tundra hauled a 10,000-pound enclosed trailer many miles with ease and stability.

I will get a lower-capacity flatbed and have someone else move the TLB if that becomes necessary.

Thanks to those who had useful feedback.

 

The two heaviest loads I haul regularly are my travel trailer (a fuzz over 7,000# loaded) and my 20’ flatbed with my tractor and a couple extra implements (about 7,600# total).

My truck is pretty heavy due to accessories, so I am technically over weight with either trailer. That said, it goes both of them wonderfully. I have had zero issues or close calls with my current setup.

I do agree with your last post though. If your TLB is 10k by itself, you’re likely in the 13-14k range with the trailer. Too much!

 

These two statements don’t go together. The smaller earlier Tundras had a max rating around 7100#. 10k would have been way too much and those early Tundras were not the best tow pigs. You’re trying to use the wrong tool for the job and justify it with bad info or experience. Be safe, get the right tool.

 

My apologies for the spare shuttle comment! Many here, myself included just like to clown around sometimes. I did state in a later more serious post that it was only a joke.
As for your equipment trailer and TLB combined, if you need to move it frequently and it's what you are describing, look at something in the HD lineup such as a 2 ton. They will have the right axles, brakes, gears, cooling system, etc. for the intended purpose. You would also need to check out the laws in your area and see if you are in need of a CDL too.
As for any year of a Tundra regardless of suspension and brake modifications, even just a skid steer and equipment trailer with the proper brakes would be way too much.
Good luck with your search for the right truck!
