Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs." on your vehicle's plac-
ard.
2. Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals
1400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of availa-
ble cargo and luggage load capacity is
650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. Consult this manual to determine
how this reduces the available cargo and lug-
gage load capacity of your vehicle.
WARNING
•
Exceeding the permissible axle weight,
gross vehicle weight, or any other weight
rating limits can cause tire overheating
resulting in permanent deformation or
catastrophic failure.
•
Do not use replacement tires with lower
load carrying capacities than the tires that
were original equipment on the vehicle
because this will lower the vehicle's GVW
rating. Use only tires with the correct load
carrying capacity. Consult your Volvo
retailer for information.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY REQUIRE-
MENTS IN ADDITION TO THESE GRADES
.
Quality grades can be found, where applica-
ble, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one half (1 ½) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and many depart significantly from the norm due
to variation in driving habits, maintenance practi-
ces and differences in road characteristics and
climate.
TRACTION
The traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance. The traction
grade assigned to this tire is based on braking
