I had the same problem before I sold my Kia, my BFG ATs would vibrate the Kia like crazy, put on my BFG MTs and it was smooth, after I bought my Jeep I put the MTs on the Jeep and new tires on the Kia to sale it, It ran smooth when I sold it. Hope thats your problem but that was alot of work getting to that point. How is your U-joints and and slip yokes on your drive shafts? Just a thought.
