Felga

Felga is the wheel rim of a vehicle, the metal ring to which a tire is mounted. It is the structural component that transmits forces from the tire to the axle and hub, supports wheel bearings, and helps position the tire bead. The rim works together with the tire, valve, and hub to form a complete wheel assembly.

Rim materials and construction vary. Steel rims are strong, durable, and often cheaper, but heavier. Aluminum alloy rims are lighter and typically better at heat dissipation, improving braking performance and handling. Rims can be one-piece or multi-piece, and may be cast, forged, or fabricated. Forged and some high-end cast aluminum rims offer higher strength for a given weight. The design and material influence ride quality, fuel economy, and performance.

Rim sizing and compatibility are defined by several specifications. Diameters are measured in inches, and widths affect tire fit. Important compatibility factors include bolt pattern (the arrangement and number of lug holes), center bore diameter, and offset (the distance from the hub mounting surface to the wheel’s centerline). Tire size must match the rim’s bead seat diameter, and the overall wheel-tire package should meet vehicle load and speed ratings.

Maintenance and safety considerations are essential. Rim damage such as bends, cracks, or severe corrosion can cause air leaks, poor sealing, or tire failure, and damaged rims often require replacement. Regular inspection, proper cleaning, and correct lug torque help prevent issues. Rim repairs are limited and many rims are replaced rather than repaired.

In summary, the felga is a key wheel component shaping performance, safety, and compatibility in modern vehicles, varying widely in material, construction, and size to suit different applications.
