Tire/Wheel Backspacing

I've read enough tire/wheel threads discussing BS and offset to make my head spin, but I need some help to ensure I'm choosing the correct wheel.

I have a set of LT315/70R17 Mickey Thompson MTZ's and I'm trying to find the correct size wheel for them.

I'm looking at a set of Unique 297's that are the same as the Cragar Soft 8's. They have only 2 options for a 5 on 5 or 5x127 bolt pattern:

Option 1 = 17x8 with 0 offset and 4.5" backspacing
Option 2 = 17x9 with 0 offset and 5.0" backspacing

Here's the link to the info: http://www.uniquewheel.com/scripts/s...ies=Series_297

Correct me if Iím wrong, but based on what Iíve read both options should ideally have .5Ē less back spacing.

I'd go with 4.5" BS just to give plenty of clearance for the wide 315 tires. I'm personally about to go with 0 offset/4.5" BS rims myself after I install my AEV 3.5" lift this weekend. Post up some pics!
