Tire ply composition and
materials used
The number of plies indicates the
number of layers of rubber-coat-
ed fabric in the tire. In general,
the greater the number of plies,
the more weight a tire can sup-
port . Tire manufacturers also
must indicate the materials in the
tire, which include steel, nylon,
polyester, and others .
Maximum Load Rating
This number indicates the maxi-
mum load in kilograms and
pounds that can be carried by the

Replacing tires or rims on
vehicles equipped with tire
pressure monitoring system
The wheels on your vehicle are
equipped with a sensor which
constantly monitors the air pres-
sure inside the tire, and then
transmits this information to the
tire pressure monitoring system.
If you are go ing to replace the
wheel rims on your vehic l e, make
sure the new rims also have these
sensors. The sensors must be
compatible with the tire pressure
monitoring system on your vehi-
cle.
If you install rims, which do not
have the sensors, or have sensors
which are not compatible, then
the tire pressure monitoring sys-
tem will not work properly . In this
case, the tire pressure monitoring
system would not be able to mon-
itor the tire pressure or warn you
if it is necessary.
-The battery inside of the tire
pressure sensor has a limited
service life.
-Always drive with the valve stem
caps securely mounted . We rec-
ommend using factory installed
