Do rims need replacing at the same time as you a new set of tires?

No, rims do not always need to be replaced at the same time as tires. Rims can usually be reused unless they are damaged or incompatible with the new tires being installed. A professional tire technician can assess the condition of your rims and determine if they are suitable for reuse. Rim damage includes: bends, cracks, dents, corrosion, major curb rash, etc. Some incompatible factors between wheel and tire are the bolt pattern, the bore and offset.
