Need advice 286 65 18

Hey all,
I have a 2014 tacoma rwd pre runner-blackout
I'm looking to have a 3" front +2"-2.5" in the rear leveling lift by toyota(warranty purposes) and adding 285 65 18 nitto trail grapplers with the fuel hostage 18" rims.. Any advice on the back spacing and mm settings? I am trying not to rub if I can help it and the least I have to trim on a new truck the better and need to minimize rubbingt the best I can.
About to add the American thunder 50 series flowmatsers also and a 30" led hidden behind the bumper so it's not visible unless it's lit up.

Any assistance with the rims would be a great help, thank you
