Infiniti Q50 wheel offset
Choosing replacement wheels for a 2015 Infiniti Q50 involves more than matching the bolt pattern and rim diameter. Wheel offset determines where the tire sits within the fender arch and how suspension and steering components are loaded. An incorrect offset can create tire rubbing, alter handling feel, or accelerate bearing wear. This article explains how offset is measured, how it interacts with rim width and tire compatibility, and what that means for clearance on this platform when evaluating aftermarket fitment options.
Essential answer
Wheel offset describes the distance between the wheel's mounting face and its true centerline, usually expressed in millimeters. A positive offset places the mounting surface toward the outside face, pulling the rim inward; a lower or negative offset pushes the tire outward. For a 2015 Infiniti Q50, the factory wheel package uses a relatively high positive offset that keeps the tire tucked under the fender while preserving suspension clearance and predictable steering geometry.
Offset cannot be judged alone because rim width changes where the outer edge falls. A wider wheel with the same offset adds width on both sides of the mounting face, so the inside lip moves closer to the strut and the outside lip closer to the fender. When comparing aftermarket options, the useful check is front and rear clearance at full steering lock and through suspension travel, not just the stamped offset number.
