123 is the single-tire service index; 120 is the index for dual-tire service. These are configuration-specific load ratings, not two numbers to add together.
Is this LT275/60R20 tire load range E or 10-ply?
Both describe its rating: load range E corresponds to a 10-ply rating. The rating is not a count of the actual casing plies.
What wheel widths are approved for LT275/60R20?
The manufacturer lists 7.5–9.5-inch rim widths for this 20-inch tire. Wheel compatibility and vehicle clearance still need checking; this size does not establish an OEM vehicle fit.
