Offsets

The offset of a wheel is the distance from the hub mounting surface to the center line of the wheel

VISUALIZE THE OFFSET

It's easiest to visualize by measuring how far the wheel's mounting face sits away from the curb

12.25 - 5.80" offset

The 5.80" positive offset means the mounting face sits 5.80" away from the wheel's center line toward the curb

Visually, this looks like about 1" from the curb

12.25 - 3.88" offset

The 3.88" positive offset means the mounting face sits 3.88" away from the wheel's center line toward the curb

Visually, this looks like about 3" from the curb

12.25 - 0.56" offset

The 0.56" positive offset means the mounting face sits 0.56" away from the wheel's center line toward the curb

Visually, this sits almost in the dead center of the wheel, or around 6" from the curb
