12.0_IDENTIFYING AND CHECKING THE RIM AND TIRE
Before you start to demount the tire, it is of CRUCIAL IMPORTANCE to identify the measurements of the rim and of the
tire. Also make sure neither is damaged.
ATTENTION: These procedures are very important and are to be performed to reduce risks of the tire bursting when
re-mounting the tire on the rim and infl ating it.
All rims bear an indication of their diameter, width, number of humps etc. If we take the picture below as an example,
you can see that:
A= 8 Nominal width of the rim in inches (1 inch =25,4 mm)
B = J Size of the fl ange
C = 15 Nominal diameter of the rim
D = H2 It indicates if there is a double hump (anti bead removing edge)
The tire bears a considerable amount of details, among which are the dimen-
sions, type and maximum speed.
For example: 205/65 R 15 91H TL
A = 205 indicates the width of the tire, in other words the distance between the
sides, expressed in millimetres.
B = 65 is the ratio expressed in percentage between the height of the section
and its width.
C = R Type of tire (R = radial)
D = 15 indicates the keying diameter in inches (diameter of wheel), which must
be the same as the rim.
E = 91 is the index of the maximum load born for each wheel.
F = H is the maximum rated speed of the tire. (H= 130,5 Mph -210Km/h)
G = TL means that the tire is Tubeless
ATTENTION: It is strictly forbidden to mount tires on rims that have different parameters
(diameter and width). It is also forbidden to mount tires with different dimensions compared
to those stated.
