Specifications
The car has whole vehicle approval. This
means that certain combinations of wheels and
tyres are approved. For the permissible com-
binations, see page 308
Wheel (rim) dimensions
Wheels (rims) have a designation of dimen-
sions, for example: 7Jx16x50.
7
Rim width in inches
J
Rim flange profile
16
Rim diameter in
inches
50
Off-set in mm (dis-
tance from wheel
centre to wheel con-
tact surface against
the hub)
Tyre dimensions
225/50R17 98W.
The dimensions are stated on all car tyres.
Example of designation:
225
Tyre width (mm)
50
Ratio between tyre wall height and
tyre width (%)
R
Radial ply
17
Rim diameter in inches (")
98
Codes for the maximum permitted
tyre load, tyre load index (LI)
W
Speed rating for maximum permitted
speed, speed rating (SS). (In this case
270 km/h).
Load index
Each tyre has a certain capacity to carry a load,
a load index (LI). The car's weight determines
the load capacity required of the tyres. Mini-
mum permitted index is specified in the table,
see page 308.
Speed ratings
Each tyre can withstand a certain maximum
speed, a speed rating (Speed Symbol; SS).
Tyre speed class must at least correspond with
the car's top speed. Minimum permitted speed
rating is specified in the table, see page 308.
The only exception to these conditions is win-
ter tyres (both those with metal studs and those
without), where a lower speed rating may be
used. If such a tyre is chosen, the car must not
be driven faster than the speed rating of the
tyre (for example, class Q can be driven at a
maximum of 160 km/h).
Traffic regulations determine how fast a car
can be driven, not the speed rating of the tyres.
NOTE
It is the maximum permitted speed that is
stated in the table.
Q
160 km/h (used only on winter tyres)
T
190 km/h
H
210 km/h
V
240 km/h
W
270 km/h
Y
300 km/h
WARNING
The car must be fitted with tyres which have
the same or a higher load index (LI) and
speed rating (SS) than specified. If a tyre
with too low a load index or speed rating is
used, it may overheat.
