Agreed!
Confirmed, I have dually 235/85/16s on the rear of my truck and 265/75/16s on the front on SRW rims, while not a different rim size, the tire's overall diameter is so close that I've had zero problems with 4wd engagement, disengagement or binding, even on dry asphalt.
There are several sets of tire sizes that are equal in diameter and can be run together.
Here are some, off the top of my head-
315/75-16 and 35x12.50-16.5
255/85-16 and 285/75-16 and 33x12.50-16.5
235/85-16 and 265/75-16 and 225/70-19.5
215/85-16 and 245/75-16
235/80-17 and 265/70-17

You can get 4000 lb load tires for your 18" wheels. This might be cheaper.
Really, I didn't know that. My truck is a 2011 Chevy D/A. Do you think my stock rims would support these heavier duty tires you speak of. Where can you get these tires?
my tires are 265/70/18
Thanks

Your stock wheels will not support those weights. You need stronger and wider aftermarket wheels to use with the larger size higher capacity tires. BFG, Toyo and Nitto all offer larger size 18" tires with higher weight ratings than your stock tires.
I have the same truck as the OP. I confirmed the width of our wheel meets the tire manuf specs for the higher capacity tire. How did you determine the factory wheel would not support 4k? What was the max? Was this the steel wheel or the aluminum?

There are no factory stock pickup wheels, either steel or aluminum, that I have every heard of that are rated anywhere near 4000 lbs. Weight capacity in the low 3000's is the norm for stock single pickup wheels.
You can go to Accuride's web site, who make most of the stock steel wheels for pickups in the US, and check for yourself the weight ratings of their wheels. The wheel rating of stock wheels doesn't usually exceed the stock tire sizes' weight rating by very much, if at all.

I tried checking the Accuride website. I found many wheels, but not the ones for the 8x180 2011+ Chevy trucks. I've also tried looking at the wheels themselves because I read that it would be stamped on the wheels. No luck there either.
This is an upgrade wheel on the 2500hd and a base option on the 3500hd. It's rear gawr is 7050lb which is the max tire limit. It is possible that the wheel is designed to carry no more than 3525 lb like the base tire. On the other hand, maybe these new 8x180 wheels are spec'd higher than the old 8x6.5 wheels.
Not sure one way or the other, but I'm definately interested in confirming. I'm not needing any extra capacity, but I like to know just what my components are capable of.
I recall a member here who runs a different size tire on the real of his 4WD 2G Dodge (I think it is white in color.) Chime in as I forget his username.

I would think that tire shops would almost have to provide this reply for a 4WD application for liability reasons. It is the "safe" answer they provide to customers no matter how knowledgeable the consumer is.
That's why you bring the rims in by themselves with another vehicle and tell them you're repairing the vehicle and needed new tires before you could move it anywhere .
I just brought in rims, ordered and bought tires. Shop never even saw the truck .

I sure would like to know the answer to this question also. I wonder how one would go about finding this answer. If anybody know please post. All though I probably would not go this route either, I sure am curious.

That's Jefe. He runs extra wide super-singles in the rear, but they are the same diameter as the fronts, or at least close enough as to not cause a problem.
For a few years, I ran 33x12.50-16.5's on the front and 285/75-16's in the rear on my 4wd F350SRW. Different sizes, but because the tires are so close in diameter, the 4wd works just fine.
