The wheels may bolt on perfectly, the pattern seemingly correct, yet the consequences are far-reaching. The scrub radius is altered, causing unpredictable steering behavior. The tires may rub against the suspension components, leading to premature wear and potentially compromising structural integrity. This seemingly minor deviation underscores a critical point: while the pattern dictates how the wheel mounts, the offset dictates where the wheel sits relative to the hub. The specification is the method of mounting but wheel offset determines where the wheel sits.
The “wheel offset” is measured in millimeters and represents the distance between the wheel’s mounting surface and its centerline. A positive offset means the mounting surface is closer to the outside of the wheel, pushing the wheel inward. A negative offset pushes the wheel outward, providing a wider stance. Zero offset means the mounting surface is aligned with the wheel’s centerline. The Toyota Sequoia’s engineers carefully calculate the optimal offset to ensure proper suspension geometry, brake clearance, and fender clearance. Deviations from this specification, even with a compatible bolt pattern, can disrupt these carefully calibrated parameters. For instance, a negative offset may cause the tires to protrude beyond the fenders, increasing the risk of road debris damage and potentially violating local regulations.
