So, I'm looking at these wheels...
 

and I'd like to purchase, but they give no info on offset or backspacing. They are ATX Artillery 18x9's.

I currently have stock 17's, no lift/level kit installed. Will these fit?

Also, the tires I'm looking at are 275/65-18...will these cause me any issues?

Thanks in advance for any assistance.

They should fit just fine. I am at stock height and run a 305 50 R20 with no issues, so a 275 65 should be fine.

Is your 2009 a 4x4 or 4x2?

4x4

They should fit easily. I'd go to American Racing website and find the specs.

part #: AX18189063212N
Offset: -12
Backspacing: 4.53

Am I good with these specs?

If the wheel specs for the 09's are the same as the 04-08's, those AR wheels will stick out about 2.5 inches farther than your oem wheels. They should work with the size you are looking at but personally I'd add a leveling kit and go with a larger tire like a 305/60-18 (33x12.50) or at the very least a 285/65-18 (33x11.50).

The wheels I posted were one of the suggestions from tirerack.com after I put in my vehicle info. I assume that means that evens 20's would fit okay since they were also suggested?

It's the overall height and width of the tire/wheel combo along with the bs that matters not the diameter of the wheel.

I see...thanks for your patience...I am finally understanding.
