The issue started immediately after rotation and has not gone away, even after returning the tires to their original positions.  The dealer replaced rotors and pads, but the vibration remained. There are no warning lights, and no visible tire damage. This condition has been reproduced by the dealer.  Upon researching, I found that Toyota issued Tech Tip T-TT-0602-20 for this exact issue \u2014 citing steering vibration caused by Dunlop Grandtrek AT20 tires on 4Runner models. I also found similar complaints from other owners on forums and the NHTSA database. The issue appears to be related to internal tire defects (e.g., belt separation or out-of-round tires) which are not externally visible.  This problem affects safety due to potential loss of steering stability at high speeds, and could worsen over time. Tires have not been replaced yet, but I plan to pursue road force balancing and a manufacturer warranty inspection. I'm glad that I was able to find this problem early before it cause tire explosion.
