have you heard of the Interco TRxUS MT?  i have had mine for a few months in a 33x12.50x15.  they are awesome.  6 ply radial.  awesome side wall treads.  drive up and grip every rock.  work great in snow and mud.  they are much better then the 32x11.5x15 bfg mud km's i used to run.  and are about $20 less per tire then the bfg's!
