A device for protecting a tire of a vehicle/conveyance such as a bicycle, a motorcycle, an automobile, etc., is provided. In general, the device includes: a ring extending beyond an outer edge of a rim of the vehicle and extending along at least a portion of a sidewall of a tire of the vehicle; and a set (e.g., at least one) 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.
