Wheels & Fitment Suggestions Wanted

Thinking about this tire/wheel combo...

For wheels, the American Racing black Teflon-coated Chamber series 3985. These can be viewed here:

I am interested in the two 16x8 wheels they have available with our 6x5.5 bolt circle. Here is the choice:

(A) 0 offset, 4.50 backspace

(B) +20 offset, 5.25 backspace (website says this fits Colorado/Canyon)

Given this, which wheel would you choose? I would like to bring the tires out to even with the fender cladding, but not exceeding that. Will the 4.50 backspacing for Wheel A push them out a bit too far? On the hand, is the +20 offset of Wheel B too much?

I am not certain on whether or not the center bore would be a problem in fitting these wheels to a VX. Chevy Colorado/GMC Canyon center bore seems to be 100.3. The VX lists at 108, but I believe I have read that the Canyon/Colorado wheels are a good fit for us. Is this true?

The tires I want to pair these with are BFG All-Terrain T/A KO, size LT255/70R16, load range D. If I remember correctly, stock wheel diameter with 245's is 29.5. The 255's would up that slightly to 30.2. Speedometer variiance would be pretty negligible, right?

My VX is a 1999 currently on stock 16x7 rims, no lift. I believe 255's are as high as I can go with no need for trimming.

I am running 265/70-16's on stock rims for winter use & they reqd. minor trimming on the front cladding.
The 265/50-20's I use for summer required me to trim a little more(same spot, just had to remove more) due to the more negative offset of the new wheels.
The backset on the dubs is 5" which brings the wheel out just slightly past the fender.
I really like the "rugged good looks" of that teflon wheel.
As far as trimming goes...don't sweat it, it's super easy to do & if you didn't know it was done, you wouldn't even notice.
Hope any of this helps.

Some good wheel reference info for figuring and converting fitments:

Wheel Terminology & Calculation (http://www.performancewheel.com/KnowledgeBase.htm)

Similar to above, different format. (http://www.eagleone.net/wheels/)

All-in-one diagram. (http://robrobinette.com/wheel_offset.htm)

Hope that helps make it clear as mud! ;)

Although I am lifted, I am running 16x8's with a +20 backspacing on my offroad set up. I am running 31x10.5 MTR's. Puts the tires pretty much even with the edge of the cladding.

Either will work, it depends on the look / function you want. The +20 offset will be closer to stock performance and look. The tires will probably sit just inside the fenders, if not flush. The 0 offset will probably protrude 1/2" or 3/4" or so. Not sure how the change in geometry will affect offroad performance. Others can probably offer better advice regarding that.
