MARKING
Example: 7 J x 16 H2 ET 43
7 = rim width in inches 1.
J = rim drop center outline (side
projection where the tyre bead
rests) 2.
16 = rim nominal diameter in inch-
es (corresponds to diameter of
the tyre to be mounted) (3 =
Ø).
H2 = "hump" shape and number (re-
lief on the circumference hold-
ing the Tubeless tyre bead on
the rim).
43 = wheel camber angle (distance
between the disc/rim support-
ing plane and the wheel rim
centre line).
