What is the center bore distance for BMW 535 wheel hubs?
2 Answers
The center bore distance for BMW 535 wheel hubs is 5x120. Wheel hub bolt pattern: The professional term for wheel hub bolt pattern is Pitch Circle Diameter (PCD), which refers to the diameter of the circle formed by the center of the lug holes. Most wheel hubs typically have either 5 or 4 lug holes, with varying distances between them. This leads to designations like 4X103, 5X114.3, and 5X112. Taking 5X114.3 as an example, it means the wheel hub's PCD is 114.3mm with 5 lug holes. Checking tire wear condition: This includes verifying whether the tires have worn normally down to the wear indicators, and checking for uneven wear patterns. Tires showing severe abnormal wear should be promptly inspected for causes and replaced. Checking for debris between tread patterns: If any debris is present, it's advisable to remove it. Leaving foreign objects embedded in the tread grooves for extended periods can cause damage to the tires.
The center bore distance, or PCD, of the BMW 535 wheel hub is standard at 5x120mm, meaning the centers of the five bolt holes are distributed on a circle with a diameter of 120mm. Over the years of driving and modifying cars, I've encountered quite a few issues. Once, I replaced the wheels with aftermarket ones assuming they were universal size, but the PCD didn't match, causing severe wobbling while driving and nearly leading to an accident. Therefore, I strongly advise owners to measure the original wheel dimensions before changing wheels or check the vehicle manual for confirmation. This specification for the BMW 5 Series has been quite stable, remaining largely unchanged since the F10 generation, but the center bore size of 72.6mm also needs attention. If the new wheel's bore doesn't align, hub centric rings must be used for reinforcement. Safety comes first—getting it wrong can lead to wheel imbalance, accelerated tire wear, or even loss of control. Regularly check the wheel hub connections during maintenance to prevent minor issues from escalating into major accidents.
