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 Capillary Refill: Push on the tip of the great toe or the nail bed until blanching occurs. 2  Then release and note how long it takes for the red color to return, a reflection of blood inflow to the distal aspect of the lower extremity. Pulses are rated on a scale ranging from 0 (not palpable) to 2+ (normal). 2  As with edema, this is very subjective and it will take you a while to develop a sense of relative values. 3  In the event that the pulse is not palpable, the doppler signal generated is also rated, ranging again from 0 to 2+.
