Speed sensitive problems like shimmies or vibrations are nearly invariably caused by a tire or wheel problem. Imperfectly balanced tire, bad tire, bent wheel, etc. That your symptoms change by changing tires is a strong indicator your tires are causing the problem. Not many tire shops will take the time to get the larger tire sizes typical to Jeeps balanced perfectly as is required. Many shops only spend enough time to get a tire balanced to what they consider "good enough" which is seldom good enough for a Jeep or truck with the type of front end they have.been reading thread, and trying to find a cause of a vibration i get at 55-65mph

I have had a driveline vibration for a little while now. I have wondered if it was tire balancing or something else. today I swapped to the original alloy wheels and 29 inch tires and at 50mph i got severe death wobble. But at the same speed with the larger tires I just got vibration. I take it the extra mass/weight of the larger tires stops the DW. Any advice would be appreciated.
