First off,
2005 fx4 with 2.5" AS in front with 1.5" AS block lift in the rear.

I am looking at a set of rims that only list offset and not backspacing and I have found several conversions but with different results. The rim specs are...

18X9 6-135 30mm offset

I BELIEVE the backspacing would be around 6.2 inches. Is that correct, and if so would that be a fit problem? Is stock not 5.5?

The tires would be Terra Grappler, LT325/60R18 unless it is possible to fit the
Terra Grappler, LT325/65R18 with only that amount of lift.

So these are my questions.
Will those rims work with the 33's?
Will those rims work with the 35's with my small lift?
My concern is inside rubbing. I will do MINOR trimming to fit 35's, and the tires sticking out isnt a problem, I like that look.

Thank you all for your help in advance.

 

I'd stick with 33's. I'm not sure what the backspacing would be either. 5 to 6 inches should work fine.

 

6.2" is correct.
