Wheels and tires -> General information for Your Volvo C30 4 Door First Generation (2006-2013)

07 Wheels and tires  
General information  
optimum road holding on icy or snow-covered  
roads, we recommend suitable winter tires on  
all four wheels.  
Introduction  
Tire rotation  
Your vehicle has no required tire rotation. Tire  
wear is affected by a number of factors such  
as tire inflation, ambient temperature, driving  
style, etc.  
Your vehicle is equipped with tires according  
to the vehicle's tire information placard on the  
B-pillar (the structural member at the side of  
the vehicle, at the rear of the driver's door  
opening).  
When replacing tires, be sure that the new tires  
are the same size designation, type (radial) and  
preferably from the same manufacturer, on all  
four wheels. Otherwise there is a risk of altering  
the car's roadholding and handling characte-  
ristics.  
NOTE  
CAUTION  
If the tires are rotated, they should only  
be moved from front to rear or vice  
versa. They should never be rotated left  
to right/right to left.  
Some Volvo models are equipped with an  
Ultra High Performance tire and wheel com-  
bination designed to provide maximum dry  
pavement performance with consideration  
for hydroplaning resistance. They may be  
more susceptible to road hazard damage  
and, depending on driving conditions, may  
achieve a tread life of less than 20,000 miles  
(30,000 km). Even if this vehicle is equipped  
with Volvo’s advanced DSTC system, these  
tires are not designed for winter driving, and  
should be replaced with winter tires when  
weather conditions dictate.  
New Tires  
Ideally, tire rotation should be done the  
first time after approximately 3,000  
miles (5,000 km) and thereafter at  
6,000-mile (10,000-km) intervals. Some  
customers find that tire rotation may  
help to get extra mileage from tire life.  
Tire rotation should only be performed  
if front/rear tire wear is fairly even and  
tread height is above 1/16" (1.6 mm).  
The tires have good road holding characteris-  
tics and offer good handling on dry and wet  
surfaces. It should be noted however that the  
tires have been developed to give these fea-  
tures on snow/ice-free surfaces.  
Your Volvo retailer can also provide guidance  
based on your particular driving circumstan-  
ces.  
Remember that tires are perishable goods. As  
of 2000, the manufacturing week and year  
(Department of Transportation (DOT) stamp)  
will be indicated with 4 digits (e.g., 1510 means  
that the tire illustrated was manufactured dur-  
ing week 15 of 2010).

Tire age  
Tires degrade over time, even when they are  
not being used. It is recommended that tires  
generally be replaced after 6 years of normal  
service. Heat caused by hot climates, frequent  
high loading conditions or Ultra Violet (U.V)  
Most models are equipped with "all-season"  
tires, which provide a somewhat higher degree  
of road holding on slippery surfaces than tires  
without the "all-season" rating. However, for

exposure can accelerate the aging process.  
The temporary spare1 should also be replaced  
at 6-year intervals, even if it has never been  
used.  
tread, these strips become visible and indicate  
that the tire should be replaced. Tires with less  
than 1/16" (1.6 mm) tread offer very poor trac-  
tion.  
Summer and winter tires  
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 altera-  
tion of the driving characteristics of the vehicle.  
A tire's age can be determined by the DOT  
stamp on the sidewall (see the illustration).  
A tire with e.g., visible cracks or discoloration  
should be replaced immediately.  
Tread wear indicator  
Improving tire economy  
Maintain correct tire pressure. For the tire  
pressure tables, see page 183.  
Drive smoothly: avoid fast starts, hard  
braking and tire screeching.  
The arrows shows the direction of rotation of the  
tire  
Tire wear increases with speed.  
Correct front wheel alignment is very  
important.  
When switching between summer and  
winter tires, mark the tires to indicate  
where they were mounted on the car, e.g.,  
LF = left front, RR = right rear  
Unbalanced wheels impair tire economy  
and driving comfort.  
Tires must maintain the same direction of  
rotation throughout their lifetime.  
Tires with tread designed to roll in only one  
direction are marked with an arrow on the  
sidewall.  
When replacing tires, the tires with the  
07  
most tread should be mounted on the rear  
wheels to reduce the chance of oversteer  
during hard braking.  
Incorrectly mounted tires impair the car's  
braking properties and ability to force  
aside rain, snow and slush.  
The tires have wear indicator strips running  
across or parallel to the tread. The letters TWI  
are printed on the side of the tire. When  
approximately 1/16" (1.6 mm) is left on the  
Hitting curbs or potholes can damage the  
tires and/or wheels permanently.

General information  
The tires with the most tread should always  
be at the rear (to reduce the risk of skid-  
ding).  
WARNING  
The wheel and tire sizes for your Volvo  
are specified to meet stringent stability  
and handling requirements. Unap-  
proved wheel/tire size combinations  
can negatively affect your vehicle's sta-  
bility and handling.  
Contact a Volvo workshop if you are  
unsure about the tread depth.  
Storing wheels and tires  
When storing complete wheels (tires mounted  
on rims), they should be suspended off the  
floor or placed on their sides on the floor.  
Any damage caused by installation of  
unapproved wheel/tire size combina-  
tions will not be covered by your new  
vehicle warranty. Volvo assumes no  
responsibility for death, injury, or  
expenses that may result from such  
installations.  
Tires not mounted on rims should be stored on  
their sides or standing upright, but should not  
be suspended.  
CAUTION  
Tires should preferably be stored in a cool,  
dry, dark place, and should never be stored  
in close proximity to solvents, gasoline, oils,  
etc.
