I put on pro comp. size 15s but I just put the same tires just black side out but I can put bigger tires on and a lift with those wheels later I just don't got the money right now.
I just ordered 16" Pro Comp alloy 7069s. They look similar to yours. And also changed over from Nitto Terra Grapplers to Duratracs. I did the same thing as you, a slow build as the $$ came in, plus the fun keeps coming with every modification.
