Definitions
Wheel Offset
Refers to how your car’s or truck’s wheels and tires are mounted and sit in the wheel wells.
– Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.
– Positive wheel offset is when the hub mounting surface is in front (more toward the street side) of the centerline of the wheel. Most wheels on front-wheel drive cars and newer rear-drive vehicles have positive offset.
– Negative offset is when the hub mounting surface is behind the wheel centerline. “Deep dish” wheels are typically a negative offset.
