Tow haul with big tires

I have a 2011 Tundra Rock Warrior with7" lift on 35s. My question is, should I be running tow haul on with the bigger tires? And if I do will it save on the transmission on daily driving?

 

What gears would be good to go with? Maybe 4.56?

 

Its wierd that you would say that. At a low speed its only 1 to 2 mph off on the speedo. I wonder if it has been regeared already.

 

Regearing has nothing to do with the speedo.

 

So how do know if it has been regeared or not?

 

Other than your butt dyno or asking the PO, not sure there’s a way to tell. Does your truck hunt for gears on the highway going uphill? The speedo won’t tell you because that just measures how fast your wheels are spinning. Putting on 35’s will increase rolling diameter by about 8%. So when you’re driving 50mph, your speedo will be off by 4mph. 2mph when you’re going 25. Regearing won’t change that.

 

Yep at 25 its 27

 

It does not hunt for a gear going up hills at all.

 

Honestly, it might not be obvious unless you’re towing or going up fairly steep at a pretty high speed. It is possible the PO regeared. But I would say more unlikely than likely. Most people who go to 37’s regear and most who go to 35’s don’t.

 

Damn you’re smart!

 

Thanks guys that helps alot. I will jack it up this weekend.

 

Will do. It will be easy to do. Esp when I build sandrails for a second job.

 

Colorado Tj what did you know? Lol. Would you like to see a pic of one that I just built?

 

Here it is

 

@ColoradoTJ since we're on the topic of regearing, at what point should we start to consider a regear? i'm assuming tire size and added weight both tie into the equation?
All I've done (so far) is went to 32.5" tire, would a regear be something i should be looking at? thinking about adding full skid plates, sliders, and bumpers in the future- maybe then it might be needed?

 

The Fresh Mouse what I have read in other threads is going past 35" tires you might want to regear.

 

that's what i thought but wouldn't 32" tires and any of the mentioned added weight also require the same?

 

I test drove a lot of tundra's before i bot this one. They were all stock. The only thing that was different was the turning radius. Other than that, no change in power.

 

When ever you want to Chris. Wife and I have 2. They run close to 100mph. The Tundra pulls them down the highway with no issues.

 

For sure. I am down
