. Speed ratings apply only to
(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 predetermined speeds.
For example, “V” means 149 mph
(240 km/h)
! 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.

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, damaged, repaired, retreaded,
or otherwise altered from
their original condition. If
tires are repaired, retreaded, or otherwise altered, they may not be suitable for original equipment

(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 represent the year. For example, 0101
means the 1st week of 2001.
! Other markings
The following makings are also
placed on the sidewall.
! Maximum permissible inflation pressure
The maximum cold inflation pressure to which this tire may be
inflated. For example, “300 kPa
(44 PSI) MAX. PRESS”
– CONTINUED –
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 2
STEEL + 2 POLYESTER SIDEWALL 2 POLYESTER”
! Uniform Tire Quality Grading
(UTQG)
The vehicle placard is affixed to the
driver’s side B-pillar.
Example:
For details, refer to “Uniform tire
quality grading standards” F13-15.
& Recommended tire inflation
pressure
! Recommended cold tire inflation pressure
For recommended cold tire inflation
pressure for your vehicle’s tires,
refer to “Tires” F12-9.
! Vehicle placard
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading information.
! Adverse safety consequences
of under-inflation
Driving at high speeds with excessively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp in-
