Well, I have 25" 589s which are small little babies i found out, and they work pretty good out there. You should be ok, just try and make sure that you don't go through someone's ruts and trya nd stay on top of the sawgrass and stuff and not in the actual mud.
You should be ok, if not, we're very patient with pulling people out
and i had my eiger back there a few weeks ago on work out stock tires and only used 4x4 a few times, so you should be ok.
