Seems I have the worst luck with Michelin tires.
4k miles on my new truck and I had a vibration, so I decided to do a road force balance. 2 tires had bad runout, one was so bad the tire guy could not get it right. I watched him remount the tire six times before I told him to give up. The other bad tire took 2 tries.
This has happened to me before withe the same tire. The at2 rock slingers. Now I have to try and convince the dealer they need replacing.
