WHEEL REPAIR GLOSSARY

  • Alloy Wheel – An automobile wheel which is made from either aluminum or magnesium metals (or sometimes a mixture of both).

  • Aluminum - A silvery-white, ductile metallic element, the third most abundant in the earth's crust. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys, like automotive rims.

  • Bend - To force a rim to assume a different direction or shape; to distort a wheel.

  • Chrome Wheel – An automobile wheel with a finish which is plated with chromium.

  • Curb Rash – The damage on a rim that is caused by scraping up against a curb. Most commonly done while parallel parking or making a u-turn.

  • Factory Requirements – Tolerances that a rim must meet or exceed to pass quality control by the original automobile manufacturer. (AKA – Factory Specifications)

  • Ghost Chrome – See Hypersilver.

  • Hypersilver - Hypersilver is a paint process that uses a silver metallic paint laid over a black undercoat to produce a finish with a deep shine. Many BMW, Infiniti, Audi and Lexus wheels have Hypersilver finishes. It is possible to refinish Hypersilver wheels, Rim ReNew specializes in this finish.

  • Lateral Bend – This bend is a side-to-side bend as you look at the wheel from the front or back of the car. A lateral bend will cause a side-to-side wobble of the rim as the wheel spins. An impact strong enough to cause a lateral bend usually causes a radial bend at the same time.

  • Machined Wheel - The surface of a machined wheel is shiny and has tiny lines in the finish which look like the grooves on a record.

  • Magnesium Wheels – An automobile wheel which is made from magnesium. While lighter than steel and aluminum wheels, they are far more expensive.

  • Marring – To make a disfiguring mark; a blemish on a wheel.

  • Metal Fatigue - The effect on metal of repeated cycles of stress. There are no obvious warning signs; cracks form without appreciable deformation of the wheel structure making it difficult to detect the presence of growing cracks. These cracks usually start from small nicks or scratches which cause a localized concentration of stress. Fatigue can be influenced by a number of factors including size, shape and design of the wheel, condition of the surface or operating environment.

  • Mounted Rim (Mounted Wheel) – A rim with a tire seated on it.

  • OEM - An automobile part is designated OEM when it is made by the same manufacturer and is the original part used when building the car. The term "aftermarket" is often used for non-OEM replacement parts.

  • Paint Stripping – Using a device or chemical substance for removing paint on a rim.

  • Polished Wheel – An alloy wheel that is polished and buffed to a high shine without any other finish on top of the aluminum (i.e. paint, chrome, etc.). Polished wheels may have a final clear coat applied.

  • Pothole - A rough hole in pavement, made by wear and weathering. Also called chuckhole.

  • Radial Bend - This is the most common type of bend. It is an up and down bend as you look at the wheel from the front or back of the car. A radial bend will cause an up and down wobble with each revolution of the wheel. Common symptoms of radial bends are feeling like one or more wheels are out of balance or a steering wheel shimmy.

  • Rim - Circular metal structure around which tires are fitted. (AKA – Wheels)

  • Rim/Wheel Repair - To renew or revitalize a rim to sound condition after damage or injury; to fix.

  • Steel Wheel – An automobile wheel which is made from steel.

  • Straighten - To make or become straight. For rims; truing or to make round, including radial and lateral truing. 

  • Tire - A covering for a wheel (rim), usually made of rubber reinforced with cords of nylon, fiberglass, or other material and filled with compressed air.

  • Tire Pressure - Inflation pressure of tires before the car is driven and the tires warmed up. Recommended tire pressure is usually found in the owner's manual.

  • Welding - To join metals by applying heat, sometimes with pressure and sometimes with an intermediate or filler metal having a high melting point.

  • Wheel - Circular metal structure around which tires are fitted. (AKA – Rims)

  • Wheel Re-Finishing – To give a new surface to a rim (wheel). Most commonly, a painted wheel is striped and repainted.

  • Wheel Refurbishment - The act of making a rim new or as if new again.

  • Wheel Restoration - The act of restoring a wheel or state of a wheel being restored, as to a former or original condition.
