Wheel offset is the distance between the wheel centerline and mounting surface, measured in millimeters. Positive offset moves the wheel inward toward suspension. Lower or negative offset pushes the wheel outward, creating more poke and aggressive stance.
Wheel poke describes how far the wheel extends outward toward the fender. Car enthusiasts often search terms like wheel poke calculator, flush fitment calculator, or will 18x9.5 +35 fit. Excessive poke may cause rubbing during turns or suspension compression.
Flush fitment means the wheel sits close to the fender line without excessive poke or inset. Many modders aim for flush wheels for aggressive aesthetics while maintaining drivability and suspension clearance.
Changing wheel width and offset changes two important things: inner clearance to suspension and outer extension toward the fender. Lower offsets increase poke. Wider wheels can simultaneously reduce inner clearance and increase outer poke.
Wheel spacers effectively reduce offset and push wheels outward. This improves stance but may increase wheel bearing load and rubbing risk. Use this wheel spacer calculator to estimate fitment before buying spacers.

Is +35 offset aggressive?
Depends on wheel width and car platform. On many performance cars, +35 with wide wheels gives aggressive fitment.
Can wrong offset damage my car?
Extreme offset changes can increase wheel bearing stress and rubbing.
Will spacers cause rubbing?
Spacers increase poke, so yes, depending on tire width and suspension height.
