Hitch rack? Your standard hanging type will be cheap and should work fine. Or you get into pricey options like the Thule t2 or the 1up. Both should fit the fat tires.
I use an old hanging style Yakima on my Jeep, and Thule side arm on the work truck.
I was gonna suggest a yak frontloader for the roof, but I am 6'2" and a stud and struggle to get my bikes loaded on top. I have a saris trunk rack I configured to mount on tailgate. I like it more than a hitch rack cuz I don't have to move it out of the way every time I need to open the tailgate.
