Hi Robert,
There are two concerns when measuring wheels. The first is the bolt
pattern and the second is the "offset" of the wheel. Bothe of these
measurements can be done with a common measuring tape.
Bolt patterns are described as the diameter of a cirle and number of
holes. Thus a four hole pattern on a four inch circle. To assess this
measure across the center hole of your original rim from one stud hope
to another center to center. compare this measurement to the rims you
are considering. If the measurement is the same the bolt battern is the
same.
The offset of the wheel is measured from the seating surface of the
inside of the wheel to the back bead of the wheel. Measure your
original wheel first. Place the wheel flat on a work surface, ie.
floor. Place a straigt edge across the center of the rear bead of the
wheel. Then measure from the inside surface of the wheel that seat
against the hub of the car to the straigt edge. This measurement is the
offset for the wheel.
Both measurements should be the same as your original wheels.
Regards,
Tom
