Enter your Current Wheel Width, Current Offset, New Wheel Width, New Offset, and Fender Clearance into the Wheel Spacer Size Calculator to find your Required Spacer Thickness, Offset Change, Inner/Outer Clearance Change, and Fitment Status.

Wheel offset is the distance between the wheel's mounting surface and its centerline. Positive offset moves the wheel inward toward the vehicle, while negative offset moves it outward. This affects how the wheel sits relative to your fenders and suspension components.
Measure the gap between your current tire sidewall and the fender at the widest point. This measurement gives you the maximum spacer thickness you can use without causing tire-to-fender contact.
Offset is measured from the wheel centerline to the mounting surface, while backspacing is the distance from the mounting surface to the inner edge of the wheel rim. Both measurements help determine proper wheel fitment.
Yes, spacers change your vehicle's track width and can affect handling characteristics. They may also put additional stress on wheel bearings and suspension components, so proper installation and quality spacers are essential.
Excessive spacer thickness can cause tire rubbing on fenders, increased stress on suspension components, and potential clearance issues with brake components or suspension parts.
Often yes, as front and rear wheels may have different offsets and clearance requirements. Always measure and calculate spacer needs for front and rear wheels separately.
Hub-centric spacers are generally preferred as they center the wheel properly on the hub, reducing vibrations and ensuring proper load distribution. They provide a more secure and balanced fitment.
