Quick answer
See where the new wheel will sit
This calculator compares wheel width and offset to estimate how far the inner and outer edges move relative to the current wheel.
The method
Understanding wheel position
Wheel width is converted from inches to millimeters. Half the width change and the offset change determine movement at each wheel edge.
Check brake, suspension and fender clearance.
A spacer reduces effective positive offset.
Measure the vehicle before ordering wheels.
Wheel offset questions
What does positive offset do?
More positive offset usually moves the wheel inward, which can reduce inner suspension clearance and reduce outer poke.
Does this guarantee wheel fitment?
No. It is a two-dimensional estimate. Brake, hub, tire shape, suspension and body clearance still need checking.
