My 2021 Telluride SX developed a severe vibration at about 3000 miles. One of my Michelin primacy tour 245 50 R20 tires had developed a bulge. Testing showed excess road force during testing, 32 lbs!. A replacement was ordered and when it arrived, it also had a defect that was picked up during balancing. Another one was ordered, balanced and installed, all at no cost to me. For another thousand miles, the ride was totally smooth at highway speed. Then I began to feel a subtle vibration. I scheduled service to look for what might be causing the vibration along with my first oil change and tire rotation. All 4 tires were rebalanced with not noticeable issues. On my drive home, the vibration was still present. Any thoughts?
