NOTE: When storing wheel/tire assemblies (e.g. winter tires and wheels), either stand the assemblies upright, or
suspend them off the ground. Laying wheel/tire assemblies on their sides for prolonged periods can cause wheel and/or
tire damage.
Wear indicator
The tires have a socalled "wear indicator" in the form of a number of narrow strips running across or parallel to the
tread. When approx. 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire should be
replaced.
Tires with less than 1/16" (1.6 mm) tread have a very poor grip in rain or snow.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.
To improve tire economy:
· Maintain correct tire pressure.
· Drive smoothly: avoid fast starts, hard braking and tire screeching.
· Tire wear increases with speed.
· Correct front wheel alignment is very important.
· Unbalanced wheels impair tire economy and driving comfort.
· If the wheels are rotated, they should be kept on the same side of the car so that they revolve in the same direction as
prior to rotation.
· Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
CAUTION: The car must not be driven with wheels of different dimensions. The use of different size wheels can
seriously damage your car's transmission.

Snow chains
Snow chains can be used on your Volvo with the following restrictions:

The spare wheel is located under the carpet on the trunk floor. The jack and crank are secured in the wheel recess.
· Engage the parking brake.
· Put the gear selector in (P)ark (automatic) or in Reverse (manual).
· With the car still on the ground, use the lug wrench to loosen the wheel bolts 1/2 1 turn. Turn the bolts
counterclocKWise to loosen.
· Fold out the crank handle on the jack by pressing the knob on the handle downward. To attach the jack, refer to the
illustration on the following page.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one that
came with the car. The use of different size wheels can seriously damage your car's transmission.
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reinstall wheels in the same location and
position as before removal. To lessen the chance of imbalance, each wheel hub is equipped with a guide stud to ensure
that a removed wheel can be reinstalled in its original position (as when changing over to winter tires/wheels).

There is a jack attachment located in the center on each side of the car. Position the jack on the bar in the attachment
as shown in illustration above and crank while simultaneously guiding the base of the jack to the ground. The base of
the jack must be flat on a level, firm, non-slippery surface. Before raising the car, check that the jack is still
correctly positioned in the attachment. Raise the vehicle until both wheels on the side of the car where the jack is
attached are lifted off the ground. Unscrew the wheel bolts completely and carefully remove the wheel so as not to
damage the thread on the studs.
Installing the wheel
Clean the contact surfaces on the wheel and
hub. Lift the wheel and place it on the hub. Make sure that you align the wheel with the guide stud on the wheel hub
prior to installation. Install the wheel bolts crosswise (see illustration) and tighten by turning lightly clocKWise. Lower
the vehicle to the ground and alternately tighten the bolts to 100 ft. lbs. (136 Nm). Install the wheel cap (where
applicable).
