Tyre speed ratings
The chart below lists many of the
different speed ratings currently
being used for passenger car tyres.
The speed rating is part of the tyre
size designation on the sidewall of
the tyre. This symbol corresponds
to that tyre's designed maximum
safe operating speed.
Speed Rating
Maximum Speed
Symbol
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y 300 km/h (186 mph)
3. Checking tyre life (TIN : Tyre
Identification Number)
Any tyres that are over 6 years old,
based on the manufacturing date,
(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 consisting of numbers and
English letters. The manufacturing
date is designated 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 indicate week and year
manufactured.
For example:
DOT XXXX XXXX 1621 represents
that the tyre was produced in the
16th week of 2021.
WARNING
Tyre age
Tyres degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom -
mend that tyres be replaced after
approximately six (6) years of nor -
mal service. Heat caused by hot cli -
mates or frequent high loading
conditions can accelerate the aging
process. Failure to follow this warn -
ing can result in sudden tyre failure,
which could lead to a loss of control
and an accident involving serious
injury or death.
