I went with the STT Pros, and so far could not be happier.
They only have about 3,000 miles and 20 trail rides on them, but so far they have exceeded my expectations.
I'm running them unbalanced, and they are happy to run 80 without a wobble. They are the quietest mud terrain tired I have had yet, and so far traction has been great.
Yeah I'm liking the looks of those geos but they look like they'd be loud. They look like mud grapplers and I loved those tires but after the set was done I never wanted another because of how loud they were.
I can't remember who it was, but there was somebody on here that fit 5 37" STTs in the back of his JLU with the HT still on. No idea how he did it.
