My jeep is running on a 2.5-3 inch lift, I want to put on the DC2's with 265/75/16 tires on. Anything on these wheels fitting with that size of tires?

How much work you want to do before installation?
What kind of lift and "actual" amounts of lift
265-75-16s = regearing ( $1500-$1600)
What the backspacing?

Lokks like only 8 inches wide, but 4 inches backspacing, too much for a KJ For instance Moabs are 8 inches wide but 5 inches of backspacing so will work, these would sit your tires / wheels out too far and have flare issues, hitting the front and rear of the flares/bumpers etc

Its running on the rockfather 1. 3" in the front 2.5" in the back.

So assuming from that you are sitting at 22 inches in front bottom of flare to middle of wheel?
If so I would stick with 245-75-16s or 265-70-16s
also wouldn't have to worry about losing so much power and mileage
