I sell these tires a lot because they are cheap, but in all honesty i hate them, they are soft, even with 35 psi they have a lot of sag in the sidewall, they rarely (from my 5+ years of dealing with them) make it to 50k miles, they wear horribly (and i doubt every ranger, astro, s10, dakota, etc i put them on has suspension issues). I hear they handle poorly as well. Honestly, I like the Uniroyal Liberator A/T (i get them at walmart) last a hell of a lot longer look better and don't suck in every weather condition.
If you want a cheaper tire, try the General Grabber AT2 I hear lots of good things about them, supposedly are better than the BFG all terrains that everyone loves for some reason, but they are cheaper also - usually not much more than the wrangler radials.
