Looking for some pictures and advice: I have a 2015 Silverado and I'm putting a RC 2'' level and a 2.25'' block in the rear (to lift it 1''). I used to have a 2009 with the same setup and I had 285/65/18 BFG's with the stock wheels. I am now thinking of running 18x9 wheels with a +1 offset in either the Fuel Pump, or the XD series 822 Monster 2's. I can't decide which wheel I like better! I also am debating running another set of 285/65/18's or 33x12.50/18's in the Toyo R/T's. Any advice on which size tire to run, and anyone have pictures of those wheel models with similar setups that they can post? Thanks in advance.

Another question about offset! I am considering buying the XD 822 Monster 2 wheel in 18x9. Does a wheel manufacturer change the depth that the middle portion of the wheel is recessed into the outside of the wheel with the change in offset? Or do they change the offset by simply changing the thickness of the middle portion of the wheel? I ask because I have seen a few pictures where the wheels look nice with a more neutral looking offset. And others where the wheel looks pretty flat and I don't like the look. I am hesitant to buy the wheel because I don't want the wheel to have a +1 offset, but still have the hub portion of the wheel sitting almost flush with the front edge of the wheel. If I buy the +1 offset, I want the center of the wheel to be more recessed into the wheel to give it some depth. Another technical question, but I hope someone understands what I'm asking!

Now I get it....Thats confusing since some site calculators calculate backspacing from the outside edge of the whee, just like you said, and others (wheel-size.com for instance) calculates it considering only the width of the seating surface. Their diagrams show that backspacing distance considers the outside edge, but their calculations don't. Thanks for the help! But that leads me to me next question...

Ok technical question guys! I am trying to figure out what my stock offset is on my 2015 Silverado Z71 w/ 18'' x 8.5'' wheels. I have found very conflicting info! 4 different place have told me 4 different things. Discount tire says its 38mm...which I believe to be true. However, I took the wheel off myself to look at it and its stamped saying the offset is 24mm. Just to confirm it, I measured it myself. And came up with 38mm! The backspacing was 5.75''...which is 146.05mm. Now here's the math.... 216mm is the total wheel width. 108mm is half the wheel width. 108mm plus 38mm (which will give you the backspacing measurement) is 146!. Which confirms my measurement. So why does the wheel have 24mm stamped on it?? And which is it? Pleeeease fill me in on how I could be mistaken. I am trying to figure out what kind of offset I want to run. And I can't make a guess until I know what I have to begin with to compare them. Thanks.
