    I love my 38x12.50"s. They steer really well in the mud.

    39"s are going to be quite a bit heavier, keep that in mind

    I have considered this myself. But, I figured for the extra 3" of tread width (12.50=10", 15=13") and the full 1.6" extra tire height (38=37.8", 39.5=39.4"), I would save the extra money. You always seem to want to go a little taller than what you have. So, my logic was, if I want 38s, I should go with 39.5s.

    39.5s are heavier, but, when aired down, they also give quite a bit more footprint to disperse the overall weight of the rig over a larger amount of surface.

    WIDER IS BETTER Lets say your truck is sideways on a smooth rock wouldnt more contact be what you want and lets say your in a deep mudhole more tread means more mud grabbedand moved to get your truck through right?I'de say 39x15 all the way.

    Wider might be better on rocks but it sure as hell isn't better in mud most times. Skinnier tires dig more so you're more in control of your rig--plus, if there's a bottom, it's much better to have narrower tires.

    I love the look of fat tires, but my next set of tires are going to be 38x12.50x15 TSLs or 38x13x16s most likely.
