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 desig-
nation on the sidewall of the tyre.This symbol corresponds to that
tyre's designed maximum safe oper-ating speed. G201003AEN-EA
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, thetyres (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 num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1606 represents
that the tyre was produced in the
16th week of 2006. G201004AUN-EA
4. Tyre ply composition and material
The number of layers or plies of rub-
ber-coated fabric are in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph) Z Above 240 km/h (149 mph)

WARNING - Tyre age
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tyres generally be replaced
after six (6) years of normal
service. Heat caused by not cli-mates or frequent high loadingconditions can accelerate the
aging process. Failure to follow
this Warning can result in sud-
den tyre failure, which could
lead to a loss of control and an
accident involving serious
injury or death.
