New Rims

Ok so I have never purchased new rims before and I am coming here for help. I have an 2007 Silverado Classic 1500 and was wondering if either one of these rims would fit my truck without modification to anything.

First one is http://www.streetdreams.org/wheel-fitment-results.php?yr=2007&mfg=Chevrolet&mod=Silverado+1500+Classic&fdiameter=20.00&ffinish=Black&fwbrand=&fstagger=&sortby=price&sortorder=asc&make=Chevrolet&model=Silverado+1500+Classic&year=2007&submit.x=59&submit.y=5
and it is the Forte F42 Haze ones. The 5th one down.

And the second one is http://www.discountedwheelwarehouse.com/Store_Detail.cfm?ID=215289&InfoID=2505&ShowLarge=True.

If anyone could help me it would be greatly appreciated. Thanks in advance.

P.S. It's a 5.3l if you need to know but I really doubt you need that.

Should fit just fine. Plenty of backspacing and a since neither are more than 8.5in wide you should fit up to a 305/50 tire with no more than trimming just a touch of the front valance.
