Rim straightening is a process used to repair bends, warping, or other deformations in vehicle rims, restoring them to their original shape and structural integrity. This technique is necessary when rims sustain damage from impacts with potholes, curbs, or other obstacles, which can cause bending or misalignment. The damaged rim is mounted onto a machine that applies controlled pressure to the affected areas. By carefully manipulating the metal, technicians can gradually reshape the rim to eliminate bends or warping while ensuring that the structural integrity of the rim is maintained.
