Correct alignment for tire and rim size

I lifted my 2017 DCLB 4x4 OR with 6112's set at 6/5 and a AAL in the rear. I got the lifetime alignment from Firestone but am unsure if the alignment is correct. On the print out everything is within spec. The alignment was done for a tire/rim size of 245/16 but my tire/rim size is 265/16. I asked the tec about this and he said he did it that way because the computer only lets him to choose from 245/16 or 265/17. He said he chose to match the rim size rather than tire size. This did not seem right to me so I just wanted to see what other people thought. My truck has settled and now my steering is a little off so I am going back to get it redone. I'm just curious since those are the only options the computer will let him choose from, which one would be better or if there is any difference at all.

 

Post up the numbers. Camber should be 0 or a little positive. Toe should be close to 0 as well maybe a smidge positive. Caster I'm not as familiar with but most I've seen around the 3.5 range. Honestly I'd be surprised if the ranges actually changed between those two wheel/tire sizes.
