dutchie, just wanted to let ya know that with my 31X11.5 Mickey Thompsons I am all over the road even with my hands on the wheel "rut diving" to the extreme. I have had it this way for so long that I am almost starting to like it ;eekr; it keeps you on your toes when driving. But once I put the stock 18"s on there again it's smooth sailing. I'm putting some new 31" studded BFG AT's on this Friday and I will see if it is as bad as my MT's.
