6-lug wheels are measured like 4-lug wheels. Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.. Note: When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured using a bolt pattern gauge. A bolt pattern gauge is a specialty tool and is not widely available.
Palpation should be done using the fingertips and intensity of the pulse graded on a scale of 0 to 4 +:0 indicating no palpable pulse; 1 + indicating a faint, but detectable pulse; 2 + suggesting a slightly more diminished pulse than normal; 3 + is a normal pulse; and 4 + indicating a bounding pulse.
1 Rate the strength of the pulse as 0 (absent), 1+ (decreased) and 2+ (normal). 2  Repeat the procedure on the opposite side. 3  Compare timing of femoral and radial pulse by simultaneous palpation. 4  Compare with abdominal aortic pulsation just above level of the umbilicus.
