A 10" wheel with 2" of backspacing has 8" of leverage to the hub face and the bearings sit a few inches behind that. Lets say 2" wide drums, and the bearing is maybe an inch behind the inside of the drum, so 11" of leverage on the bearing.

A 10" wheel with 8" backspace has 6" less leverage on the bearing. That's a significant difference in weight multiplication on the bearing.
