To once again veer one of my own threads, what's the deal with the low profile tires? I'm seeing them on quite a few 4X4s. A buddy with a new 4Runner has them as well. Are they just being put on the, as Charby alludes to, "4Xs" that don't go offroad? I don't really know anything about them, other than I see them on a lot of street vehicles. I would think they would not be good offroad tires because for one thing, it doesn't seem like you have much leeway if you want/need to lower the air pressure for certain conditions.
