Easily. As mentioned, you can fit 33x12.5s with simple, minor modification. The key is getting the right rims.

I have a 2" body-lift and a 2" suspension lift and am only running 33x12.5s (waiting for them to wear out). If I'd wanted, I could fit 39s with some rubbage (I've scoped it out). My next set of tars will be 35s. 37s would be more than I care with which to task the axles.
