The data shown in the illustration is sample
data.
Maximum permitted tire pressure
1
, which is per-
mitted for the tires must not be exceeded.
Exception: when using the 225/75 R16C
121/120R (122L) tires as a spare wheel on the
rear axle of Super Single vehicles with a distance
limit of 62 mi (100 km) and speed limit of 34 mph
(55 km/h).

Tire size designation, load-bearing capacity and
speed rating
&
WARNING Risk of injury through exceeding
the specified tire load-bearing capacity or
the permissible speed rating
Exceeding the specified tire load rating or the
permissible speed rating may lead to tire dam-
age and to the tires bursting.
#
Therefore, only use tire types and sizes
approved for your vehicle model.
#
Observe the tire load rating and speed
rating required for your vehicle.

The size ratio between the tire height and tire
width and is shown in percent (tire height divided
by tire width).

"R": radial tire
Rim diameter
5
:
The diameter of the bead seat (not the diameter of
the rim flange). The rim diameter is specified in
inches (in).
Load-bearing index
6
and
7
:
Numerical code which specifies the maximum
load-bearing capacity of a tire ("91" equals, e.g.
1,356 lb (615 kg)).
The tire load-bearing capacity must be at least half
the permissible axle load of the vehicle. Do not
overload the tires by exceeding the maximum per-
missible load of the tires.
