Tundra mpg disparity theory...

I believe our mpg's disparity might be from our tire/wheel combination, my aluminum wheel weighs 33.5 lbs and my tire is 39 lbs for a total of 72 lbs.

What are your wheel combo weights and am I off track?

There are also substantial differences in weights between the various body styles. A stripper regular cab standard bed 2WD versus a fully loaded Crewmax 4x4 for example.

I weigh 700 lbs.

True, the model difference's would matter. But we constantly see people with like models getting 3 mpg's less on the freeway. I'm sure the engine assembly line differences can't be the problem.

I picked 4x2 over 4x4 for mpg's since in the past I rarely used 4x4.

I have 4 kids and a wife to weigh down my ride. Haven't checked to see what it would be without them.

DC RW package with 285/75/17 Nitto Terra grapplers, my wife, two daughters, two small dogs and my fat azz from our house to Pagosa Springs & back including a trip into town for shopping yielded over 17 mpg. Not sure exactly how much as I haven't fueled up yet, but just over half a tank for 240+ miles is damn good for a full size truck running 65 up and down mountains.

I wear steel toes boots a lot and the weight forces my foot down on the accelerator But seriously my highways probably vary from yours.

When they built the one I mainly drive on they apparently couldn't afford overpasses, so there's a ton of lights which kills my mpg's compared to driving on an interstate with off ramps, etc.

There's so many small variables and to me it's just not worth worrying over mpg's because I have to drive the truck or lose depreciation and buy a fuel efficient vehicle. Just my .02

Tires have a lot to do with fuel mileage.
The biggest killer of mileage is friction.
Friction caused by the larger foot print of bigger and wider tires.
If you have 2 identicle tires and the only difference is width, the wider one will give you poorer fuel mileage.

You have greater friction due not only the increased contact patch on the pavement but also increased wind resistance while driving down the road due to the wider tire.

Pretty simple physics really.
You want better mileage put skinny little tires on your truck.

Perhaps, but it would depend on what each stone weighed.

Stone (unit) - Wikipedia, the free encyclopedia
Anywhere from 5 pounds to 40kg depending on who's measuring.

You nailed it. (the original) Mr. Creosote was from England and weighed himself in stones.
When I moved here and applied for a driving license I told the woman at DMV my weight in stones, she said "like what!"

Where did that British fellow go? I should have asked him if he knows Clarkson.

About a thousand different things figure into mileage. Just off the top of my head: Weather, gas formulation, the truck's body-style, driving style, traffic pattern, wheel and tire size and weight, how much junk you carry in the truck. Unless you can say every single variable in your situation is exactly the same as every single variable in the next person's situation, you may not get the same mileage. If you don't have much stop and go with these trucks high teens is very attainable. If you are always stopping and going expect to see 11-13 mpg.
