Load index
8 8:
R "Light load": light load tires
R "C": commercial tires Information on definitions (tires and load‐
ing)
Ti re stru ctu reand characteristics: describes
th e number of la yers or the number of rubber-
coated la yers inthe tire tread and the tire wall.
These are made of steel, nylon, pol yester and
ot her materials.
Bar: metric unit for tire pressu re.
14 .5038 pounds per square inch (psi) and
10 0 kilopascals (kPa) are the equivalent of 1 bar.
DOT (Department of Transportation): DOT
mar ked tires fulfill there qu irements of the
U. S. Depa rtment of Transpor tatio n.
Av erage weight of vehicle occupants: the
number of occupants for which theve hicle is
designed multiplied by150 lbs (68 kg).
Un iform Tire Quality Grading Standards: a uni‐
fo rm standard tograde thequ ality of tires with
re ga rdsto tread quality, tire traction and temp er‐
ature characteristics. The quality grading assess‐
ment is made bythe manufacturer in accordance
with test specifications of theU. S. go vernment.
The quality grade of a tire is imprinted on the
side wall of the tire.
Re commended tire pressu re:there commen‐
ded tire pressure is the pressure specified forthe
tires ins talled on theve hicle at thefa ctor y.
The Tire and Loading In form ation placard con‐
ta ins there commended tire pressures for cold
tires, the maximum permissible load and the
maximum permissible vehicle speed.
The tire pressure table con tains there commen‐
ded tire pressures for cold tires under various
operating conditions, i.e. load and/or speed of
th eve 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
ins talled.
GA WR (Gross Axle Weight Rating): GAWR is the
gross axle weight rating. The actual load on an
axle mu stneverexc eed the Gross Axle Weight Ra
ting. You can find the Gross Axle Weight Rating
on the 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 includes thewe ight of theve hicle includ‐
ing fuel, tools, the spare wheel, accessories
ins talled, occupants, luggage and the trailer
dr aw bar nose weight if applicable. The Gross Vehi‐
cle Weight must ne verexc eed the Gross Vehicle
We ight Rating (GVWR) specified on the B-pillar on
th e driver's side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
th e 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 theve hicle's curb
we ight, weight of the accessories, maximum load
and thewe ight of thefa ctory ins talled optional
equipment.
Kilopascal (kPa): metric unitfor tire pressu re.
6.9 kPa are the equivalent of 1 psi. Ano ther unit
fo r tire pressu reis bar. 100 kilopascals (kPa) are
th e equivalent of 1 bar.
Load index: in additiontothe load-bearing index,
th e load index may also be imprinted on the side‐
wa ll of the tire. This specifies the load-bearing
capacity 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
th ese 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 appro ved.
Maximum permissible tire pressure: maximum
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 for one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressu re. Wheels and tires
