BOLTING YOUR WHEEL TO THE HUB
Different styles of wheels use different styles of lug nuts.
Aluminum or Mag wheels sometimes use a flat face
or a rounded face nut. Steel wheels including wire wheels usually use a beveled edge nut.
Make sure the nut is the same diameter and thread as the stud. Chevrolet normally has a 7/16-20 stud where Ford and Mopar
use a ½ x 20 stud. Way back when, some cars used RH and LH thread. This is very uncommon, but watch for it.
When bolting the wheel on, it’s best to seat a lug nut snugly on each stud before tightening. To uniformly seat the wheel
on the hub go around the wheel in a sequence (every other nut on a 5 lug wheel) tighten a little more each round until the
correct torque specification is met.
Using the wrong lug nuts or not tightening them properly could result in you being in the ditch with sheared studs as your
tire heads on down Route 66 into the sunset without you.
BOLT PATTERNS
This pattern is expressed as the diameter of an imaginary circle that passes through the center of each bolt hole regardless
of the number of holes. 4, 5, 6 & 8 lug wheels are all measured in this way. The expression 5 on 4½ just means that there are
5 holes equally spaced around a 4½" diameter circle.
Measuring the bolt pattern on a 4, 6 or 8 lug wheel is pretty simple. Just measure from
the center of any hole to the center of the hole directly opposite and you’ve got it.
On a 5 lug wheel, go from the center of any hole across the center to a point midway
between the centerline of the two opposite holes.
Remember also that Ford and Mopar use a larger stud so the
lug hole in the wheel is larger than GM's.
