What size you running? I ran them in 265/75-16 which was basically 32x10.50 and I had great luck with them. They were very tough tires, and they wore perfectly as the miles racked up. I loved them.
I bet your alignment is way off in the front end. Either that or your wheel size doesn't match tire size very well.

My favorite quote from the press release.. sad but true: "Chrysler claims its products, especially the Jeeps, can handle all sorts of terrible conditions, churning through muddy swamps, climbing mountains, and crossing rivers. Turns out they cannot even handle a car wash."
