Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specific
government test course. For example, a tire
graded 150 would wear one and a half (1-1/2)
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 may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction AA, A, B, C
The traction grades, from highest to lowest, are
AA, A, B, and C and they represent the tire's ability
to stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Warning!
The traction grade assigned to this is based
on braking (straight-ahead) traction tests
and does not include cornering (turned)
traction, acceleration, hydroplaning or peak
traction characteristics. Temperature A, B, C
The temperature grades are A (the highest), B and
C, representing the tire's resistance to the
generation of heat and it
s ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperatures can cause the
material of the tire to de generate and reduce tire
life, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the labora tory test wheel than the
minimum required by law.
Warning!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combin ation, can cause heat
buildup and possible tire failure, resulting
loss of control, leading to serious personal
injury or death.
Tire pressures
Danger!
Risk of accident.
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases risk of a tire failure and resulting
loss of control. Furthermore, low tire
pressure increases rate of wear of the
affected tires and cause damage.
f Always use an accurate tire pressure gage
when checking inflation pressures.
f Do not exceed the maximum tire pressure
listed on the tire sidewall. (Also refer to
”Technical data“).
f Please see the chapter “TIRE PRESSURE
PLATE” on page 283.
f Cold tire inflation pressure means: all tires
must be cold, ambient temperature maximum
68 °F (20 °C), when adjusting the inflation
pressure. Avoid sunlight striking the tires
before measuring cold pressures, since the
pressures would rise from temperature
influence.

A Seating capacityMaximum number of vehicle occupants,
including the driver.
B Vehicle load limit Is the maximum total weight limit specified of
the load (passengers and cargo) for the
vehicle. This is the maximum weight of
passengers and cargo that can be loaded into
the vehicle.
Please see the chapter “LOADING
INFORMATION” on page 236. C Original tire size
Size of tires mounted at the factory.
D Recommended cold tire inflation pressure These values are for cold tires (68 °F/20 °C).
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may bu ild up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause
partial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surfaces to prevent this.
Tire lifeTire life depends on various factors, i.e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
f Inspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.Tire wearThe original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the tires.
We recommend, however, that you do not let the
tires wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

Snow tiresThe installation of Porsche approved snow tires is
recommended.
Use Porsche approved snow tires for grip on snow
and ice.
Check with your local Motor Vehicle Bureau for
possible restrictions.
Danger!
Risk of loss of control and damage to the
vehicle as well as serious personal injury or
death.
The standard tires profile and rubber mixture
are optimized for wet and dry driving
conditions, and may not prove favorable for
snow conditions.
f Install snow tires before driving in such conditions.
Before mounting snow tires, consult with your
Porsche dealer. They have the technical
information necessary to advise you on wheel and
tire compatibility.
f Snow tires should have the same load capacity
as original equipment tires and should be
mounted on all four wheels.
Danger!
Risk of serious personal injury or death.
Driving the vehicle with low tire pressure
increases increases risk of a tire failure and
resulting loss of control. Furthermore, low
tire pressure increases rate of wear of the
affected tires and cause damage.
Tires with badly worn treads and studs are
very dangerous and could cause accidents
resulting in serious pe rsonal injuries or
death.
f Make sure they are replaced immediately.
f Do not exceed the snow tire speed rating.
Snow tires do not have the same degree of
traction on dry, wet or snowfree roads as normal
tires.
Furthermore, snow tires wear rapidly under these
conditions. Maintenance note
We recommend fitting winter tires on the vehicle at
temperatures below 45 °F (7 °C) since the driving
performance of summer tires is reduced at low
temperatures. Summer tires may be permanently
damaged at extremely low temperatures.
Winter tires do not fulfill their purpose if the tread
depth is less than 5/32 in. (4 mm).
Comply with all state and local laws
governing snow tire and tread depth
requirements.
Danger!
Risk of accident and serious personal injury
or death due to excessive speed.
f Always check the maximum speed rating on
the tire sidewall on any tire on the vehicle.
f Never exceed the maximum speed rating of the tires.
Wheel change
f When wheels are removed, mark the direction
of rotation and position of each wheel.
Example: FR (front right), FL, RR and RL.
f Always fit the wheels in accordance with the
markings.
