Are the Krawlers red label or blue? Blues are decent all around tires. Reds are awesome in the rocks but suck in the snow so you really need a second set of tires if you do snow wheeling. Plus the reds wear out pretty quickly. I ran blue 35's for a few years and they were pretty decent all around tires. I also ran 37" radial Iroks and 39.5" bias Iroks. I don't have anything bad to say about either Irok. For an all around tire, my 39.5 bias Iroks have been great. I don't have any experience with the 41" radials.
$780 for Krawlers?????
What's your intended wheeling? Sand, rocks, mud, snow? None or some of the above?
