I have a jeep with a set of 39.5 IROK on it that may change your mind he walks up pretty much every thing he points it at you need bead locks so you can air down to 4 pounds or so and they are really good. I do have other tires to compare them to also, a set of comp. trepadors, a set of comp. bgf's, a set of pitbull rockers and a set of comp. mickey thompsons. All and all I would say the iroks do pretty good.
