Depends on if your lifted or not. Those tires stick out quite a bit anyways but i dont think spacers will be needed. Just do a 2inch lift and they should fit just fine with a small about of trimming. But a word of warning, I bought the 28 10.50 front and 28 12.50 rear and the 10.50 arnt as tall as the 12.50, i guess HLP dident get the mold just right or something but iv ordered a pair of 9.5s for the front since their the same height. Its not a real big height difference but if you look at my pics you can tell what im talkin about.
