Roller cone drill bit with evenly loaded cutting elements

A drill bit for drilling through earthen formations and forming a wellbore, the drill bit comprising:

• a bit body having a bit axis;
• at least a first cone and a second cone coupled to the bit body, each of the first and the second cone having a backface and a nose opposite the backface;
• a first array of first cutting elements coupled to at least one of the first or second cones between the backface and the nose, a tip of each first cutting element being located in one of a plurality of radial positions defined by a radial distance from the bit axis and a bottom hole depth relative to the bit axis, and a number of first cutting elements located at a first radial position having a maximum bottom hole depth within the first array being greater than a number of first cutting elements located at a second radial position having a lesser bottom hole depth within the first array;
• and
• a second array of second cutting elements coupled to at least one of the first or the second cones between the backface and the nose, wherein a tip of each second cutting element is located in one of a plurality of radial positions, a number of second cutting elements located at a third radial position having a maximum bottom hole depth within the second array being greater than a number of second cutting elements located at a fourth radial position having a lesser bottom hole depth within the second array.
