Wheels are also marked with impor-

ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:

6.0 - Rim width in inches.
J - Rim contour designation.
15 - Rim diameter in inches.
Tyre speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tyre size designa-
tion on the sidewall of the tyre. This
symbol corresponds to that tyre's
designed maximum safe operating
speed.

Maintenance
3. Checking tyre life
(TIN : Tyre Identification
Number)
Any tyres that are over 6 years,
based on the manufacturing date,
tyre strength and performance,
decline with age naturally (even
unused spare tyres). Therefore, the
tyres (including the spare tyre)
should be replaced by new ones. You
can find the manufacturing date on
the tyre sidewall (possibly on the
inside of the wheel), displaying the
DOT Code. The DOT Code is a
series of numbers on a tyre consist-
ing of numbers and English letters.
The manufacturing date is designat-
ed by the last four digits (characters)
of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tyre size and tread
pattern and the last four numbers indi-
cate week and year manufactured.
For example:
DOT XXXX XXXX 1619 represents
that the tyre was produced in the
16th week of 2019.
