Biggest tire under a stock suspension 3/4 ton 4x4

What is the biggest tire that will fit under a stock 87 ¾ ton 4x4

I'm wanting to remove my Superlift kit and my 315-75-16 tires and go to a lower heigth.

Some of this question can depend on the width of the tire and the backspace of the rim.

I do not have an exact answer as my truck has bigger tires but I'm sure others that have researched this will answer.

You want to remove a lift kit? Isn't that kind of like getting a vasectomy? Removing some of your manhood? 
Seriously, Just funnin with ya !!!!

Yeah that does sound pretty dumb!!!  The reason I was thinking of doing this was to plow snow with it. But I've re-thunk it over  and I'm going to just keep the 4" lift. Then after I ware out the 315-75-16 Fearce MT's I might go down a tire size or two with a set of AT's of some kind???

     I can see your thinking on the plowing snow, but I really don't think it would matter much.  The best thing like you said is when you wear out the tires you have go to a lower tire and I think it would do better.
     A member on here named Blazin (I believe I am correct) does plowing with his truck, he would be a good one to ask.

305/70/16 -  Kind of an expensive size though to buy.

Don't know how different the height will be from your truck to mine, but my 78 C20 with a 2" lift, max size is a 275/70R18 and I had to nip a bit off the front bottom of the wheel openings in the front fenders.
