G WARNING
Overloade dt ires can overheat ,c ausing a
blowout .O verloade dt ires can also impair the
steerin ga nd driving characteristic sa nd lead
to brak ef ailure. Ther eisar isk of accident.
Observe th el oad rating of th et ires. The load
rating must be at least half of th eG AWR of
your vehicle .N ever overload th et ires by
exceedin gt he maximum load.
Two instruction labels on your vehicle show the
maximum possible load.
(1) The Tire and Loadin gI nf ormation placar di s
on th eB -p illar on th ed river' ss ide. The Tire
and Loadin gI nf ormation placar ds hows the
maximum permissible number of occu-
pant sa nd th em aximum permissible vehicle
load. It also contain sd etails of th et ir es izes
and corresponding pressures for tires
mounted at th ef actory.
(2) The vehicle identification plat eisont he
B-pillar on th ed river' ss ide. The vehicle
identification plat ei nform sy ou of th eg ross
vehicle weight rating .Itism ade up of the
vehicle weight ,a ll vehicle occupants, the

mation about th em aximum gross axle
weight rating on th ef ront and rear axle.
The maximum gross axle weight rating is
th em aximum weight that can be carried by
one axle (front or rear axle) .N ever exceed
th em aximum load or th em aximum gross
axle weight rating for th ef ront or rear axle.

The gross weight of all vehicl eo ccupants, load
and luggage must not exceed the specified
value.

Maximu mn umber of seats C indicates the
maximu mn umber of occupants allowe dt o
travel in the vehicle. This information can be

Determinin gt he correct load limit
Step-by-ste pi nstructionsThe following steps have been developed as
required of all manufacturers under Title 49,
Cod eofU .S. Federa lR egulations, Part 575 pur-
suant to the "National Traffi ca nd Motor Vehicle
Safety Act of 1966". X
Step 1: Locate the statement "The combined
weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on you rv ehicle’s
Tire and Loading Informatio np lacard.X
Step 2: Determine the combined weight of
the drive ra nd passengers that wil lber iding in
you rv ehicle. X
Step 3: Subtract the combined weight of the
drive ra nd passengers from XXX kilograms or
XXX lbs. X
Step 4: The resulting figure equals the avail-
abl ea mount of cargo and luggage loa dc apa-
city. For example, if the "XXX "a mount equals
1400 lbs and there wil lbef ive 150-lb pas-
sengers in you rv ehicle, the amount of avail-
abl ec argo and luggage loa dc apacity is
650 lbs (1400 -7 50 (5 x1 50) = 6 50 lbs).X
Step 5: Determine the combined weight of
luggage and cargo being loaded on the vehi-
cle. That weight may not safel ye xceed the
available cargo and luggage loa dc apacity cal-
culated in step 4.
Example :s teps 1to3The following table show se xamples on how to
calculate total and cargo loa dc apacities with
varying seating configurations and number and
size of occupants. The following examples use a
loa dl imi tof1 500 lbs (680 kg). This is for illus-
tration purposes only. Make sure you are
using the actua ll oa dl imi tf or you rv ehicl es tated

Quality grades can be found ,w here applicable,
on the tire sidewall between tread shoulde ra nd
maximum sectio nw id th.
Example: R
Treadwear grade: 200R
Tractio ng rade: AAR
Temperature grade: A
All passenge rc ar tires must conform to the stat-
utory safety requirements in additio ntot hese
grades.
i The actua lv alues for tires are vehicle-spe-
cific and may deviate from the values in the
illustration.
Treadwear The treadwea rg rad eisac omparativ er ating
based on the wea rr ate of the tire whe nt ested
unde rc ontrolled conditions on as pecified U.S.
government course. For example, at ire graded
150 would wea ro ne and one-half times as well
on the government test track as at ire graded
100.
The relative performance of tires depends upon
the actua lc onditions of their use ,h owever, and
may depart significantly from the norm du et o
variations in driving habits, service practices
and differences in road characteristics and cli-
mate.
Traction
G WARNING
The tractio ng rad ea ssigne dtot his tire is
based on straight-ahead braking traction
tests, and doe sn ot include acceleration, cor-
nering, hydroplaning ,orp ea kt ractio nc har-
acteristics.
! Avoid wheelspin. Thi sc an lea dtod amage to
the driv et rain.
The tractio ng rades –f rom highest to lowest –
are AA, A, Ba nd C. Thos eg rades represent the
tire's ability to stop on wet pavement as meas-
