The hub bore is 106.00 but 99% of aftermarket wheels are lug centric although you might be able to get hub centric rings for them.
MHT Fuel wheels are offered in 106.4 mm bore sizing. They're a good option.
That'll work well for you. I'm a fan of the Fuel "Gauge" rims myself.These are the wheels I want with the specs:
Fuel D530 Hostage - Chromel by Fuel Off-Road
FUEL D530 Hostage Wheel 20x9
Bolt Pattern 6 on 5.5
Finish = Chrome
Backspace = 5
Center Bore 106.4
MaxLoad 2200
Offset = 1
Yup those will definitely work well. What size tire are you going with??
Yup good choice on 275's, the 285's might give you some rubbing without a lift. You also may want to consider those wheels in 20x9 -12 offset, these will give you a little wider stance and I think you'll like the look. Just a suggestion.
