Jim, I have seen how you drive your H2, and there is no doubt in my mind that your 37s are NOT the cause of any of your issues you are having now. I think, "I drive my vehicle pretty damn hard," is an understatement from you.
I have seen you drive through the **** faster than I would on an ATV. Undoubtedly you are finding the limits of your truck, and more power to you. It is a great experience wheeling with you guys. Make sure to always give me a heads up when you go.
Back to the tires. I have heard a few folks mention a little rubbing, but certainly you have had the loudest complaint I have heard yet. I just want to make sure I am happy with 37s on my truck when/if they get installed. It seems to me that your experience with the 37s is a little different than others' and I am just trying to figure out why that is and the only reason I can think of is clearance.
From this last weekend out and your before and after comments, I can see what difference 37s make in a real off road situation.
