BMW 328i xDrive unstable handling on old highways, possible tire issue on BMW 328i xDrive

Some BMW 328i xDrive owners report experiencing unstable handling on old highways, which may be attributed to issues with their tires. This unpredictable handling, often referred to as "tram lining," can occur when using tires installed with the Sport package. While stock run-flat tires are commonly a concern, some owners find them satisfactory; however, it is crucial to maintain proper tire pressures as recommended by BMW and to verify tire specifications, especially after a recent tire change. If handling issues persist despite these checks, it is advisable to have the ABS sensors, wiring, and DSC unit inspected for potential damage or faults, as these steps could help diagnose and resolve the instability.
