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.
Most people can see the faint bluish line of their radial artery; place your fingertips here. Count the beats for 1 minute. Or, if you have a short attention span, count for 30 seconds and multiply by 2. During your workout, take your pulse about every 15 minutes and be sure to concentrate. You may want to slow down or even stop while you take your pulse.
