I'd suggest some craigslist wrangler take-offs since you're running 5x5 pattern and looking to stay budget friendly. (sell? ) Many folks buy new fancy shmancy pavement pounder Jeeps and sell very capable MT 31/32s. usually you'll see wheels and tires together so don't buy rims if you haven't already.

my 31s stuffed pretty damn well before I got trigger happy with a cut-off wheel on the sheet metal. I recommend a little fender trimming. puts a big smile on your face
