Dimension designation for tyre
Designations for tyre dimension, load index
and speed rating.
The car has an approval for the complete vehi-
cle with certain combinations of wheel rims
and tyres.
Designation of dimensions
All tyres have a dimension designation, such
as: 235/60 R18 103 V.
235 Tyre width (mm)
60
Ratio between tyre wall height and
tyre width (%)
R
Radial ply
18
Rim diameter in inches
103
Codes for the maximum permitted
tyre load, tyre load index (LI)
V
Speed rating for maximum permitted
speed, speed rating (SS). (In this
case 240 km/h (149 mph).)
Load index
Each tyre has a certain capacity to carry a
load, a load index (LI). The car's weight deter-
mines the load capacity required of the tyres.
Speed rating
Each tyre can withstand a certain maximum
speed. Tyre speed rating, SS (Speed Symbol),
must at least correspond with the car's top
speed. The table below shows the maximum
permitted speed for each speed rating (SS).
The only exception to these regulations is win-
ter tyres
2
, where a lower speed rating may be
used. If such a tyre is selected, the car must
not be driven more quickly than the tyre is
rated for. For example, cars with Q rating tyres
must be driven at speeds not exceeding
160 km/h (100 mph). The road conditions and
applicable road traffic rules determine how
quickly the car can be driven, not the speed
rating of the tyres.
The maximum permitted speed is specified
in the table.
Q
160 km/h (100 mph) (used only on
winter tyres)
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)
WARNING
The lowest permitted load index (LI) and
speed rating (SS) for the tyres for each
respective engine variant are shown in the
car's registration document. If a tyre with
too low a load index or speed rating is
used, it may overheat and be damaged.
