11.0_IDENTIFYING AND CHECKING THE RIM AND TYRE
Before you start to demount the tyre, it is of CRUCIAL IMPORTANCE to identify the measurements of the rim and of the
tyre. Also make sure neither is damaged.
ATTENTION:
These procedures are very important and are to be performed to reduce risks of the tyre bursting when
re-mounting the tyre on the rim and inflating 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 =24.5 mm)
B = J Size of the flange
C = 15 Nominal diameter of the rim
D = H2 It indicates if there is a double hump (anti bead removing edge)
The tyre 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 tyre, 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 tyre (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 admitted speed of the tyre. (H= 210Km/h)
G = TL means that the tyre is Tubeless
ATTENTION:
It is strictly forbidden to mount tyres on rims that have different
parameters (diameter and width). It is also forbidden to mount tyres with different
dimensions compared to those stated in the logbook.
