I didn’t mention this on my first response because the post was already long, but the same thing happened to me years ago with a set of KO2s on an F-350 that I had. I couldn’t get the shake to go away. It was determined that one or more of the tires had belts that had either shifted or broken. Once again, replacing the tires (that time with Michelins) eliminated the shake.I had a set of BFG’s on one of my F150 4x4’s that would balance out perfectly at my brother-in-laws tire shop, then after I would drive 150-200 miles they would vibrate so bad I couldn’t stand it. After about 4 different rebalances I was able to get them replaced by BFG. Cause, broken belting in the tires.
A vibration at 60-65 mph is 99% of the time caused by a balance issue, period.
Someone on this forum told me that BFG used a different compound years ago that would harden with age. Perhaps this was the problem.
I wonder if I’m the only one who’s had this problem with more than one set of BFG KO2s. ‘Surely not! Maybe others will respond.
