The TIN is a unique identification number to
identify tires and comprises thefo llowing:
RDOT (Department of Transport ation):tire
symbol mar ks1 indicating that the tire
complies with therequ irements of the US
Department of Transpor tation.
RManufacturer identi fication code: manu‐
fa cturer identification code 2contains
de tails of the tire manufacturer. New tires
ha ve a code with two symbols. Retreaded tire
ha ve a code with four symbols. Further infor‐
mation on retreaded tires (
→pa ge 358).
RTire size: identifier 3describes the tire
size.
RTi re type code: tire type code 4can be
used bythe manufacturer as a code to
describe specific characteristics of the tire.
RManufacturing date: manufacturing date
5 prov ides information about the age of a
tire. The 1st and 2nd positions represent the
calendar week and the 3rd and 4th positions
st ate theye ar of manufacture (e.g. "3208"
re presents the 32nd week of 2008).
Information on the maximum tire load
%
The data shown in the image is example
data.
Maximum tire load 1isthe maximum permissi‐
ble weight for which the tire is appr oved.
Do not overload the tires by exceeding the speci‐
fi ed load limit. The maximum permissible load
can be found on theve hicle's Tire and Loading
Info rmation placard on the B-pillar on the driv‐
er's side (

Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side
wa ll of the tire.
Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.
The tire and information table conta insthere c‐
ommended tire pressure for cold tires, the maxi‐
mum permissible load and the maximum permis‐
sible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressure for cold tires under various
operating conditions, i.e. loading and/or speed
of theve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle, re
ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
mounted.
GA WR (Gross Axle Weight Rating): the GAWR
is the maximum gross axle load. The actual load
on an axle must ne verexc eed the gross axle
we ight rating. The gross axl e
we ight rati
ng can
be found on theve hicle identification plate on
th e B‑pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the gross vehicle
we ight comprises thewe ight of theve hicle
including fuel, tools, the spare wheel, accesso‐
ri es ins talled, occupants, luggage and the trailer
dr aw bar nose weight, if applicable. The gross
ve hicle weight must not exceed the gross vehicle
we ight rating GVWR as specified on theve hicle
identification plate on the B‑pillar on the driver's
side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The gross vehicle weight rating is speci‐
fi ed on theve hicle identification plate on the
B‑pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of the unladen
we ight of theve hicle, thewe ight of the accesso‐
ri es, the maximum load and thewe ight of
optional equipment ins talled at thefa ctor y.
Kilopascal (kPa): metricunit for tire pressure .
6.9 kPa cor responds to1 psi. Ano ther unit for
tire pressure is bar.100 kilop ascal (kPa
) equals
1 bar.
Load index: in additiontothe load-bearing
index, the load index may also be imprinted on
th e side wall of the tire. This specifies the load-
bearing capacity of the tire more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air
conditioning sy stem and optional equipment if
356
Wheels and tires

these are ins talled on theve hicle, but does not
include passengers or luggage.
Maximum tire load: the maximum tire load is
th e maximum permissible weight in kilog rams or
lbs for which a tire is appr oved.
Maximum permissible tire pressure: maxi‐
mum permissible tire pressure for one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated bydividing the maxi‐
mum axle load of one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressure .
Aspect ratio: ratio between tire height and tire
width in pe rcent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the tire.
The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be cor rected when
th e tires are cold.
Cold tire pressure: the tires are cold when the
ve hicle has been par kedfo r at least 3 hours without direct sunlight on
the tires or theve hicle
has been driven for less than 1 mile (1.6 km).
Ti re contact sur face: the part of the tire that
comes into con tact wi th thero ad.
Ti re bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel
ri m. There are se veralst eel wires in the bead to
pr eve nt
the t
ire from coming loose from the
wheel rim.
Side wall:the part of the tire between the tread
and the tire bead.
We ight of optional equipment: the combined
we ight of the optional equipment weighing more
th an there placed standard parts and more than
5 lbs (2.3 kg).This optional equipment, such as
high-per form ance brakes, le vel control sy stem, a
ro of luggage rack or high-per form ance batte ries,
is not included in the curb weight and thewe ight
of the accessories.
TIN (Tire Identification Number): a unique
identification number which can be used bya
tire manufactu rerto identify tires, forex ample,
in a product recall, and thus identify the pur‐
ch asers. The TIN is made up of the manufactur‐ er's identity code, tire size, tire type code and
th
e manufacturing date.
Load-bearing index: the load-bearing index
(also load index) is a code that con tains the max‐
imum load-bearing capacity of a tire.
Tr action: traction is the grip resulting from fric‐
tion between the tires and thero ad sur face.
We ar indicator: narrow bars (tread wear bars)
th at are distributed overth e tire conta ct surface.
If th e tire tread is le vel with the bars, thewe ar
limit of 1/ 16in (1.6 mm) has been reached.
Distribution of vehicle occupants: distribution
of vehicle occupants
over design
ated seat posi‐
tions in a vehicle.
Maximum permissible pa yload weight: nomi‐
nal load and luggage load plus 150 lb (68 kg)
multiplied bythe number of seats in theve hicle.

maximum transmission output of up to2 W
