What does wheel offset mean on an ATV?
Offset is the distance from the wheel's centerline to the mounting face. It controls how far the tire sits from the hub.

How it works
A smaller (more negative) offset moves the wheel outward. Track width changes by twice the offset difference, converted to inches.
Track-width change per side in mm = current offset − new offset. New track = current track + 2 × that change.

Wheel Offset Calculator FAQs
Will more track width help stability?
A wider stance can feel more stable, but it can also load bearings, hit fenders, or change steering effort.
Is ATV offset the same as automotive ET?
The idea is similar, but ATV wheels are often described with different measuring points. Use the numbers from your wheel maker.
