CORRECT RIM READING

Below, please find the instructions need-

6.5 = rim width in inches (1)
J = rim drop centre outline (side pro-
jection where the tyre bead rests)
(2)
16 = rim nominal diameter in inches
(corresponds to diameter of the
tyre to be mounted) (3 =
H2 = "hump" shape and number (relief
