FUEL Off road D517 Krank Wheels Help??

Hey guys Need some Help with buying my Wheel and choosing tire.

-Going to buy Suspension soon (Icon or King).

-Definitely going to buy Fuel Wheels d517 Kranks.
These are 17x9. My problem is which offset? 1 or 20?
20 has 5.75 of backspacing
1 has 5in backspacing.

-My second issue is which size tires can i use for these 17x9 wheels
I was thinking 33's and going 285/70/17
or maybe staying stock with 265/70/17

will any of these two tire sizes work?

 

Need to check on your new Suspension set up I think Max Back Space is 5" on the new UCA & C/O your going to get

 

I think you're right. 5" max.

 

can i put 285/70/17 tires on the 17x9 wheel?

 

I have Fuel Frontier 17x9 +20 265x70x17 no spacers and no rubbing.
