No pull with my STT's or my friend's set in 37" variety. Those km2's sucked royally on wet roads.

The firestone isn't a bad tire, it just lacks siping that helps with anything wet or this freak snow we're getting recently.

My offer of a test drive on the stt still stands and tomorrow I'm picking up a set of used mtrk's to see what they're all about.

I've wheeled with a couple guys running the Pros in 37. Great in rocks, mud, and snow with good price. I'm running MTRK and they compare favorably.
