A cast wheel is poured into a mold from a molten alloy, while a forged wheel is formed under pressure from a solid aluminum billet. A forged wheel is lighter and stronger than a cast wheel of the same size, but it costs more.
Bolt pattern (PCD) is the number of bolts and the diameter of the circle they are arranged on, for example 5×112. Like the center bore DIA, it is listed in the vehicle specifications; the easiest way is to ask a tire shop to measure the stock wheel.
ET is the distance in millimeters from the wheel mounting surface to the center of the rim. Offset determines whether the wheel will stick out past the fender or hit the brake caliper; the value is usually stamped on the inside of the wheel.
Many cars have factory staggered wheels. For example, in the R22 model set for BMW X5 G05, the front wheels are 22×9,5 ET22 and the rear wheels are 22×10,5 ET28, so these wheels are sold as a set of 4 pcs.
Yes, forged wheels are made to order: you can choose a design from the catalog or send a photo, and the manager will match the diameter, width, offset, and bolt pattern to your car.
No, the package includes only the wheels. Tires and tire pressure sensors are selected separately, and the center caps are chosen according to the wheel center bore diameter.
Forged Wheels vs. Cast Wheels: Pros and Cons
Lighter than cast wheels of the same size — lower unsprung mass
Denser metal structure: better at absorbing impacts and retaining shape
You can choose the design and set the width, offset, and bolt pattern for your car
Available in large diameters — up to R24, including staggered sets
More expensive than cast wheels of the same diameter
Made to order — not an off-the-shelf purchase
You need to know the car’s exact parameters (PCD, ET, DIA, width)
