HOW TO READ THE
RIM DATA
Example: 6 J x 14 ET 40
6 = rim diameter in inches (1).
j) = rim drop centre outline (side
projection where the tyre bead
rests) (2).
14 = rim nominal diameter in inches
(corresponds to diameter of the
tyre to be mounted) (3 = Ø).
ET = shape and number of humps (used
for withholding tubeless tyre
beads on the rim).
40 = wheel camber angle (distance
between the disc/rim supporting
plane and the wheel rim centre li-
ne).
