Needs tires.
It has 265 75 16's now. What in standard or metric size will fit (as in bigger)with no lift, on factory wheels?

Also

Thinking ahead, may do some towing with this truck. But not at all confident with the weak little 10 bolt rear end. Thinking I could swap in a semi float 14 bolt in the 6 lug variety, to add a little beef to the part taking the brunt of a load.
I figure it's pretty much bolt in, but I have been wrong. Anyone with experience, please chime in
 
I had a Tahoe in that year range, if I remember right I had 285's on it. Took the airdam off cause then tire would grab it at full lock and slightly flexed. I might have cranked the T bars a little, but not a lot because I didn't want a rough/jouncy ride since my wife was the primary driver.
 
^^^ thats what I'd do. You shouldn't have any trouble clearing 285's and they'll fill the fenders nice. If you dont want to take the air dam off you can just trim the corners of it right where it wraps around to towards the tire.
 
Yep I did 285 on my wife's Yukon & just took the front air dam off under the front bumper.
 
The 14 bolt SF should be a bolt in deal. You may need a conversion u-joint though, but not entirely sure.
 
As mentioned, 285s are an easy direct fit on stock wheels, minor trimming of the air dam possibly. The 14sf is a direct bolt in, the u-joint depends on the shaft you have stock, aluminum or steel, IIRC they are precision #448 or #447.

Also, when looking for a 14SF, the best option would be to find one from a 1/2 ton "heavy half" (RPO code F44 in the glove box), these are 6 lug and the correct width. 6 lug 14SFs in the vans are the correct width but the perches will need to be moved. 6 lug 14SF from a 2wd light duty 2500 are 4" narrower, they are a direct bolt in, but you will need 2" spacers to even up the width. 8 lug 14SFs are the correct width and perch width, all it takes to make them 6 lug is swap the shafts and drums (or redrill).
