I am looking at getting 33x12.50x15 duratracs with Level 8 Tracker wheels. I am thinking of this combo because of the savings in weight. I had read a few posts saying that the 15x8 would be better for offroading because they can be aired down further than 15x10, however, the tread on the tire will not wear evenly. My offroading is limited to the beach and the occasional Rausch trip. I was wondering if this is the case and how severe the uneven wearing will be.
