Audi Q7: Wheels and Tires
General information
- Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
- If driving over curbs or similar
obstacles, drive slowly and approach
the curb at an angle.
- Have faulty tires or rims replaced
immediately.
- Protect your tires from oil,
grease, and fuel.
- Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
- Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
WARNING
Note
- Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recommends
winter tires during the
winter months. Low temperatures
significantly decrease
the elasticity of summer tires,
which affects traction and
braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
- Burnished, polished or
chromed rims must not be
used in winter driving conditions.
The surface of the rims
does not have sufficient corrosion
protection for this and
could be permanently damaged
by road salt or similar
substances.

number, the wider the tire.
- Aspect ratio
Height/width ratio expressed as a
percentage.
- Tire construction
"R" indicates a radial tire.
- Rim diameter
Size of the rim diameter in inches.
- Load index and speed rating
The load index indicates the tire's
load-carrying capacity.
The speed rating indicates the
maximum permitted speed. Also
see > in General information.
"EXTRA LOAD", "xl" or "RF" indicates
that the tire is reinforced or
is an Extra Load tire.
P up to 93 mph (150 km/h)

- US DOT number (TIN) and
manufacture date
The manufacture date is listed on
the tire sidewall (it may only appear
on the inner side of the tire):

more layers, the more weight a
tire can carry. Tire manufacturers must also specify the materials
used in the tire. These include
steel, nylon, polyester and other
materials.
- Maximum permitted load
This number indicates the maximum
load in kilograms and
pounds that the tire can carry.
- Uniform tire quality grade
standards for treadwear,
traction and temperature
resistance
Treadwear, traction, and temperature
ranges.
- Running direction
The arrows indicate the running
direction of unidirectional tires.
You must always follow the specified
running direction.
- Maximum permitted
inflation pressure
This number indicates the maximum
pressure to which a tire can
be inflated under normal operating
conditions.
