That's why I prefer looking at backspace only, I've used that calculator and gotten different results with the same values.

I'm looking at Method Wheels:

The 17x8.5 shows a 0mm offset and a 4.72" backspace.

The 17x9 shows a -12mm offset and a 4.25" backspace.

According to the calculator a 9" wide wheel with a -12mm offset would be a 4.5" backspace. That seems to be a common measurement with 9" wide wheels. Yet tirerack says different.

I was going to go with the 9" wide for the shallower 4.25" backspace. I'm assuming the difference from stock of 1.25" means the wheels would be pushed outward that far? Maybe a little more since the rim is 0.5" wider?

I'm going to call tirerack before I order but I'm ready to pull the trigger. I'm so tired of trying to find used wheels!
