A device for protecting a rim of a vehicle/conveyance such as a bicycle, a motorcycle, an automobile, etc. is provided. In general, the device includes a ring for abutting and protecting an outside edge (along an outer circumference) of a rim, and a plurality of wings for securing the ring to the rim via insertion of the wings between the rim and a tire mounted on the rim. In one embodiment, the ring and/or each wing may be made of one or more materials such as a rubberized material, a plastic material, a composite material, or any combination thereof. Moreover, each wing typically comprises a wedge shape body having a set of engagement peaks for inserting and securing the wings between the tire and the wheel (e.g., before or after the tire has been mounted on the rim).
