I have been doing a 5 tire rotation on my 2015 until recently. This summer, one of my rotations resulted in a really bad vibration. I assumed I had thrown a weight. After a visit to a tire shop, I was told that particular wheel ( formerly in the spare position) was calling for over 14oz of weight.
I've been wondering if the pressure from the mounting pads on the back of the Jeep could have created a "cup" condition in combination with high temps and / or sun and time on the back of the Jeep.
Anyone else have similar conditions or experiences? I'd like to get my overall wear and mileage back, but not at the expense of horrible vibration.
