Ply Rating/Load Range
While there is no industry-wide definition of ply
rating, truck tires are frequently marked with ply
rating and equivalent Load Range. These markings are
used to identify the load and inflation limits of that
particular tire, when used in a specific type of
service. The table shows the conversion of tire
markings.

 PLY   LOAD
RATING RANGE
  2      A
  4      B
  6      C
  8      D
 10      E
 12      F
 14      G
 16      H
 18      J
 20      L
 22      M
 24      N

All "C" (or "D") rated tires don't necessarily have
the same load rating. Michelin shows 7 "C" rated LTX
M/S tires in various sizes, each with a different load
rating (from 93 to 113).

Looks to me like the alpha load range designations
have more to do with sidewall ratings than the actual
numerical load rating of the tire.
