I think your offset is creating a few more interference issues than a stock wheel would, but good to know.
Good point r.e. wheel offset. My 275/70/18 (33") don't rub even on my 12mm offset wheels. On full compression, the tires make it JUST inside the fender arch. Going to a 295/70/18 with the same 12mm offset might introduce an interference problem with the fender arch. Hadn't really considered that.
