My friend has them on a full size blazer and they seek to do alright.  They are a prettty cheap tire, he has 36: bias ply.  It is like 12.5 or 13.5  but they are actualy wider than a 14.5 bogger.

  He has had them for about one year and it is his daily driver, cant tell much wear but he really dosent wheel.   

If you get them I agree with FatAssRunner, go with a bias ply.
