advice on new wheels

I've got a 2016 with the TSS Offroad package and the "OEM" flares that the dealer added - it came with 285/55/20 BFG KO2s. Right now I've still got stock suspension. Everything fits fine but I'm not in love with the tucked in look. I'm probably going to have to replace the tires soon and will probably get new rims at the same time. Looking for advice on offset - I'd like to push them out a little closer to even with the flares. Looks like I need about 1.5 inches. I'm thinking of moving to an 18" rim and a 285/65/18 KO2, but would like a bigger tire if I can make it fit w/o too much work. Any ideas & advice greatly appreciated! thanks!

 

I would go 3/1 on suspension and run 295/70/18

 

OP, does that package come with a lift/leveling kit already? Some of them I've seen with that package already come with a lift. I would say for wheel offset, go with a +18mm to a +25mm and you should be good. The OEM flares don't stick out quite as far as the bushwackers.

Let's see a picture of your truck and may help with the tire size. I do think that you will be able to go bigger than the 285/65/18 though.
