Ans: A bent rim refers to physical damage or deformation in the wheel's structure itself, often caused by impacts with potholes or curbs. It can result in vibrations, handling issues, and uneven tire wear. On the other hand, an unbalanced tire refers to an uneven distribution of weight around the tire and rim assembly. It causes noticeable vibrations at certain speeds but doesn't necessarily involve physical damage to the rim. Both issues can affect ride comfort and vehicle performance but require different solutions, with bent rims often needing repair or replacement and unbalanced tires requiring balancing.
