Hey I have a chance to get 2018 ford edge 21 inch wheels, same offset bolt pattern and hub size, but is 9 inches wide and with 245 35 21 is 27.8 tall and stock is 215 70 15 26.9 tall, would the 21 set up fit?
You have it backwards. Offset is the measurement from the dead centerline of the wheel to the mounting face of the wheel. The bigger the positive offset the farther away from the centerline it is, ergo the closer the whole wheel is to the chassis.
its usually noticeable visually too, when viewing a wheel from an angle a high offset wheel’s spokes will appear basically flat from the rim to the hub. Lower offsets will often have a concave or dished appearance where the center and spokes appears sunken in relation to the rim.
