Rim offset (ET) is a parameter defining the distance between the mounting surface of the rim and its axis of symmetry, expressed in millimeters. The ET value determines how deep the rim is embedded in the wheel arch. With a positive ET, the rim is deeper in the wheel arch, while with a negative ET it protrudes more outwards. A correctly selected offset is crucial for the stability of the vehicle's driving, avoiding friction on the suspension elements and ensuring the appropriate appearance of the car.

Rim center hole is the hole in the very center of the rim that fits onto the vehicle's hub. Its diameter must match the hub diameter so that the rim is properly seated and centered on the vehicle. The center hole plays a key role in transferring loads from the rim to the hub, which affects driving stability and safety. If the center hole is too large, centering rings are used to ensure a proper fit.

Rim flange profile refers to the shape and construction of the rim edge that comes into contact with the tire. Flange "J" is characterized by the appropriate shape and dimensions that ensure the tire is securely seated on the rim, minimizing the risk of the tire slipping while driving, especially at low pressure or with high lateral loads. This profile is widely used due to its versatility and ability to work with different types of tires.

Rim cross-section profile refers to the shape of the inner part of the rim, which includes both the flange and the surface on which the tire rests. This profile is critical to proper tire seating, mounting, and overall fit to the vehicle hub. Rim cross-section profile H is a rim with one hump on the inside of the rim. This hump helps prevent the tire from coming off the rim, especially when driving with low tire pressure or during sudden maneuvers.
