Wheel Nuts - Volvo 2007 S40 Owner's Manual

The spare tire in your car is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar or on the fuel filler door) should be maintained irrespective
of which position on the car the temporary spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible by a standard tire. Road holding and handling may be affected
with the "Temporary Spare" in use. Do not exceed 50 mph (80 km/h). Do not drive farther than 50 miles (80 km) on
a temporary spare tire.
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.

Wheel nuts

Types of wheel nuts
There are two different types of wheel nut, depending on whether the wheels are steel or aluminum.
Steel rims - low nut
Steel rims are normally secured using the low type of nut, although steel rims may also use the high type.
WARNING
Never use the short type of nut for aluminum wheels. This could cause the wheel to come loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is considerably different from other types of nut
because it has a rotating conical thrust washer.
