ok...this might be a little different from what you were expecting but hear me out..
Look into General Grabber AT2s 275-65-18 they are exactly the same diameter as stock but they are about 1" wider and they have much nicer tread. These tires are also pretty well rated. Good thing is they only weigh 2 pounds more then stock...no real excess wear and tear on your drivetrain..
Now for step 2...get some TeraFlex 1.25" spacers to push the wheels out a little wider, giving a fuller more agressive stance...
Step 3 (optional) you could "Plasti-dip" your stock wheels..making it "look" like you got new wheels WITHOUT having to pay for them...do a search on the forum..plenty of info and pics on Plasti dip .. it's basically a black paint, not glossy, that you can do it yourself..it comes in a spray can..and best thing is, if you change your mind..you can peal it off
I like this idea for wheels cuz you know your stock wheels are well made, and are made to work on YOUR vehicle..
I'd say this route, all-in (tires+spacer+Plasti dip) would run you about $1,000
i have some tire pics attached..i just put the Grabber At2s on my 2013..totally changed the look..i DO NOT have spacers (yet)...i took it to show my salesman, he said "looks like you put a little lift on it"
