Hi,i need some advice on what offest to consider before buying the xd rockstar wheels 20x8.5.
I want my wheels to be flush with the fender flares (bush-waker pocket style 2")
My current wheels are the stock 265/60/18 as found in the below pic.

Looking forward for your input.

This is what i will be going for along with NITO A/T 305/55/20

What do you think?

Do the flares stick out exactly 2" past the current wheels? If so, you would need to go to at least a 0 offset, if not a negative offset for the wheels to be even with the flares.

I'm not sure how wide the factory 18's are, but if the Rockstars are a 0 Offset and .5" or more wider than the factory wheels, it should be close to even. The factory wheels are about a 42-44 offset.

-12

You reckon -12 will flush the wheels with the flares? Would it be risky to go for -24??

On bush-waker website it states that" this flare offers up to 2 " of the tire coverage.

Going from factory wheels to -24 offset would move the wheel about 2.5" outward. Then, if your new wheel is any wider, you'd have 1/2 that difference to add also.

I think a -24 is too wide, unless you want the wheel to be outside the flare.

Yes, and yes.

I personally think it looks goofy if the tires don't stick out past thef fenders. I'm not talking about a ghetto mexican look, but just enough to not look stupid. I hate the looks of a tire that is inside the fender *chevy *cough* *chevy*. But a -24 would most definitely stick out of those flares. If my math is correct, a -12 should be just about perfect (depending upon the actual width of the tire)

The tires im going for is 305/55/20.
You think it will level perfectly.
Appreciate your input by the way.

Well that's a 33x12 tire, so on a 8.5" rim I would estimate that the tire would hang over the edge of the wheel approx 1.75" on each side. Since the stock wheels are 7.5" wide with 31x10.5 tires, that means they hang over the edge of the stock wheel approx 1.5" on each side.

With those numbers above, we can conclude that since the wheel you are wanting is 1" wider, it will stick out 1/2" more on the outside (1/2" on each side). Then, since the new tires are 1.5" wider, that adds another .75" on each side. That's 1.25" so far (.75" + .5") Then, add another 1.75" (assuming a -12 offset) to account for the new wheel offset, and that adds a total of 3" to the outside vs stock (.75" + .5" + 1.75" = 3"). So, to verify this, all you need to do is park your pickup on a level surface, (at least level on the horizontal x axis, or the "roll" axis if you know anything about aircraft) hang a plum line down from the ouside of your fender flare, and then measure the distance from your stock tire out to the plum line. If it's approx 3", you're in luck. If not, then based off of that same measurement, adjust the offset of the wheel that you plan to purchase in order to coinside with your desired look.
