*Measuring: [348.15 (5m)] The distances between the foremost and rearmost of a group of axles shall be measured between axle CENTERS to the nearest even foot, and when a fraction is exactly one-half foot, the nearest larger whole number shall be used.
Example: 50 feet 5 inches = 50 feet; 50 feet 6 inches = 51 feet
Axles must be at least 42 inches apart to qualify as a separate axle and must bear at least 8 percent of the Gross Vehicle Weight (GVW).
