I will second this as I have a few weeks now on my 33x12.5/15's on stock alloys. Discount, Sears, Costco... places like that will tell you it can't work or it will tear up the tires fast. I used to run 33x12.5s on stick Tahoe 7" wide wheels too and I always got great life out of the rubber. I think the biggest problem you would have on the narrower rims is the shop guys do not pay any attention and will over-inflate them. I almost wonder if they do it to purposely wear tires fast. Who knows. At this point I say pick a wheel you like more than anything, but yes, you will have some light rubbing so be prepared. My side lugs are pretty aggressive (Duratracs), so it was a bit of a shocking noise at first!
