The Beyern Spartan BMW wheel is available in sizes including 17-inch, 18-inch, 19-inch and 20-inch diameters. In each size, two widths are available, giving BMW drivers the added option of specifying a staggered footprint. In a staggered footprint, the rear wheels and tires are wider than the front setup. This giver the vehicle a more aggressive stance, and improved off the line and lateral acceleration.
Beyern BMW Wheels are engineered for precise and perfect fitment to the full range of BMW models, and offers variations in each wheel diameter and width for three important variables. Pitch Circle Diameter is the diameter of an imaginary circle drawn through the center of the wheel’s boltholes. A precise PCD ensures a stable, vibration-free ride. Offset is the difference between the actual mounting plane of the wheel and its physical center. Accurate offset is essential to assure the tire and wheel fit inside the wheel well without interfering with suspension, brake or body components. Finally, Bore is the diameter of the center hole that fits over the vehicle’s center hubs. BMWs have either a 72.56mm or 74.1mm bore.
