The 15 x 7.5 inch black machine face inner lip red alloy wheels with the specifications 4x100 PCD, 4 lugs, and ET 20mm offset are described as follows:
 
 
Size (15 x 7.5 inches):
 
 
Diameter: The wheel has a 15-inch diameter.
 
Width: The wheel is 7.5 inches wide.
 
This size is commonly used for compact cars, small sedans, and performance vehicles, offering a balance of handling, agility, and a lightweight structure.
 
 
 
 
PCD (Pitch Circle Diameter 4x100):
 
 
PCD refers to the bolt pattern, indicating the number of bolts and the distance between them. This wheel has a 4 bolt pattern, with the holes spaced 100mm apart.
 
The 4x100 bolt pattern is common for small and compact vehicles, such as models from Honda, Toyota, Nissan, and Hyundai.
 
 
 
 
Lugs (4 Lugs):
 
 
4 Lugs means the wheel has 4 bolt holes, used to secure the wheel to the vehicle. This is compatible with the 4x100 PCD pattern, ensuring proper fitment with compatible vehicles.
 
 
 
 
ET (Offset 20mm):
 
 
ET (Offset) represents the distance between the wheel's mounting surface and its centerline. A 20mm offset means the wheel’s mounting surface is pushed 20mm outward from the centerline.
 
This offset is suitable for vehicles that need a slightly wider stance or an aggressive look, improving the vehicle's overall appearance and stability.
 
 
 
 
Design:
 
 
Black Machine Face with Red Inner Lip: The wheel features a black machine face with a red inner lip, creating a striking contrast. This design is popular for sports cars and modified vehicles, providing a bold, sporty appearance and visual appeal.
 
 
Summary:
 
Wheel Size: 15x7.5 inches (diameter x width).
 
PCD: 4x100 (4 bolt holes, spaced 100mm apart).
 
Lugs: 4 lugs (bolt configuration).
 
ET (Offset): 20mm (mounting surface pushed 20mm outward).
 
Design: Black machine face with red inner lip for a unique and sporty look.
These wheels are ideal for compact cars, small sedans, or modified vehicles, offering a distinctive black-and-red design along with an aggressive stance. The 20mm offset provides a wider look, enhancing both appearance and handling, making them a great choice for those seeking performance and style upgrades.
