北米Model "A1700BE-B" EDITED: 2017/ 10/ 11
Example:(6) Load Index: A numerical code
which specifies the maximum load
a tire can carry at the speed
indicated by its speed symbol, at
maximum inflation pressure.
For example,“90”means 1,323 lbs
(600 kg),“89”means 1,278 lbs (580
kg).
WARNING
Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire’s rated
load.
(7) Speed Rating: An alphabetical
system describing a tire’s capability
to travel at established and prede-
termined speeds.
For example,“V”means 149 mph
(240 km/h)
WARNING
.
Speed ratings apply only to
the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire’s rated speed.
.
The speed rating is void if
the tires are worn out, da-
maged, repaired, retreaded,
or otherwise altered from
their original condition. If
tires are repaired, re-
treaded, or otherwise al-
tered, they may not be sui-

!Tire Identification Number (TIN)Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of
four groups. Here is a brief review of
the TIN with a breakdown of its
individual elements.
(1) Manufacturer’s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the
week, starting with“01”to represent
the first full week of the calendar
year; the second two figures repre-
sent the year. For example, 0101
means the 1st week of 2001.!Other markingsThe following makings are also
placed on the sidewall.
!Maximum permissible infla-
tion pressure
The maximum cold inflation pres-
sure to which this tire may be
inflated. For example,“300 kPa
(44 PSI) MAX. PRESS”

!Maximum load rating
The load rating at the maximum
permissible weight load for this tire.
For example,“MAX. LOAD 580 kg
(1279 LBS) @ 300 kPa (44 PSI)
MAX. PRESS.”
WARNING
Maximum load rating applies
only to the tire, not to the
vehicle. Putting a load rated
tire on any vehicle does not
mean the vehicle can be
loaded up to the tire’s rated
load.!Construction type
Applicable construction of this tire.
For example,“TUBELESS STEEL
BELTED RADIAL”
!Construction
The generic name of each cord
material used in the plies (both
sidewall and tread area) of this tire.
For example,“PLIES: TREAD 2STEEL + 2 POLYESTER SIDE-
WALL 2 POLYESTER”
