Tread wear
WARNING - Tyre age
5. Maximum permissible inflation
pressure
The tread wear grade is a compara-
tive rating based on the wear rate of
the tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded
100.
The relative performance of tyres
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
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 loading
conditions 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.
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.

6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
These grades are moulded on the
side-walls of passenger vehicle
tyres.The tyres available as standard
or optional equipment on your vehi-
cles may vary with respect to grade.

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

Uniform tyre quality grading
Quality grades can be found where
materials in the tyre, which include applicable on the tyre sidewall
steel, nylon, polyester, and others. between tread shoulder and maxi-
mum section width.
For example:
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
