So whoever said and doubted you couldnt put 37's on with a leveling kit was wrong! I got 37x13.50x18 toyo open country MT's on Ultra Stargazer rims which are 18x9 with a -12 offset. I have a 2.5" leveling kit up front with 2" add-a-leafs in the rear. I would not have done my truck any other way, it came out exactly how i wanted it too.... I love the way it looks with a leveling kit and 37's. I did have to pull my inner fenders back about 3 inches, but that was nothing. Otherwise there is absolutely no rubbing whatsoever, even when my truck is articulated a little. Here are some pics, sorry they were taken with my iphone. I have 2 front center caps that are on their way to cover my front 4x4 hubs.... but i love the way it looks so much i couldnt wait for those things to get here to take a couple quick pics.
Before shot with 35 Nitto AT's (which are garbage, never getting them ever again!)
After with the 37's
