Has any one used Pro Comp tires? They show a 33/12. 5R/17 in an All Terrain. It is rated high in several off road magazine articles. I have used the BF Goodrich AT/KO's on an older Ford F-350 gasser but I am looking for replacement tires for my 03 CTD QC 4X4 6spd with 3. 73 3/4 ton. BFG offers a 285/70R/17 that is also under consideration. I don't want to go any bigger. Thanks in advance.
