Many of today’s wheels are cast or forged and made out of steel, aluminum, or aluminum alloy. Casting consists of pouring liquid metal into a mold, while forging consists of heating and machining a wheel into shape through the use of CNC lathing equipment. Anatomy-wise, the center section of a wheel contains a bolt pattern and mounting holes that are used to attach the wheel to a vehicle. The outermost lip of the wheel is known as the flange. The flange, located on the edge of the wheel, is flared to form the bead seat, which holds the tire and maintains an airtight seal. Safety humps are small elevations on the inside of the bead seat, which prevent the tire from falling into the drop center portion of the wheel in case a blowout occurs. This innovation allows drivers to maintain directional control of a vehicle with deflated tires. The drop center is the section of the wheel with a smaller diameter than the rest of the wheel. The drop center provides a means for installing and removing a tire. If you are looking for a one-stop wheel and rim shop, you have come to the right place.
