Information
If a tire is damaged and it is not possible to determine with absolute certainty that there is no ply damage
- with all of its consequences - or if the tire was thermally and/or mechanically overloaded due to a loss of
pressure or other prior damage, replace the tire in question for safety reasons.
Repairs to "V", "W", "Y" and "ZR" tires are not permissable, as well as the use of inner tubes in tubeless
tires. Please inform your customers accordingly. It is advisable to mount winter tires at temperatures
below 45° F/7°C , because the driving characteristics of summer tires are reduced at low temperatures.
Extremely low temperatures can cause permanent damage to summer tires.
WARNING
Incorrect tire pressure
•

Uncontrollable vehicle handling



Adjust the tire pressure according to specifications. Never allow the pressure to fall below the minimum
pressure.



Check age of tires. Replace tires that are more than 6 years old.



Perform visual inspections.



Use only tires recommended by Porsche.

Tire Pressure:
Information
The tire pressure applies only to the tire makes and types approved by Porsche, and is specified for cold
tires (approx. 68° F/20°C ). The tire pressures must never be lower than the specified values.

Wheel Storage: •
•
•
•
•
•
•
•

General
Information:

•
•
•
•
•

Tires must be stored in a cool, dry and dark room with adequate ventilation.
Tires must never come into contact with fuel, oil, grease or chemicals.
Do not store summer tires in storage areas with ambient temperatures of less than 5° F (-15° C).
Complete wheel & tire assemblies can be stacked for storage; we recommend that you increase the
tire pressure by approximately 6 psi (0.4 bar).
Optimum conditions for storage of the complete wheels are provided by the Original Porsche
storage trolley, Part No. 000.044.000.38.
If the tires are not mounted on wheels, it is best to store them in a vertical position.
We recommend that you turn tires stored in this position every two weeks in order to prevent flat
spots.
Tires that are stacked in a horizontal position will become severely deformed and cannot be seated
properly in the rim flange when they are mounted.
Always use new valves when changing tires.
Always observe any possible instructions concerning the rolling direction and/or specifying which
side the tires must be mounted on.
Coat the tire beads and humps with mounting lubricant before mounting the tire. This ensures that
the tire beads will slide over the humps easily.
In order to prevent the tire from turning on the wheel, avoid extreme driving maneuvers (acceleration
and braking) during the first 100 to 200 miles with new or recently mounted tires.
In order to optimize smoothness of rolling, it is appropriate - and necessary in individual cases - to
mount the tire in a certain (favorable) position with respect to the wheel (matching).

Matching (uncontrolled and controlled) is explained below: Uncontrolled matching:
•

Turning the tire on the wheel by 90° or 120° if necessary in order to achieve an acceptable value with
regard to rolling smoothness (true running, imbalance and weight distribution of balance weights).

Controlled matching:
•

•

•

With a balancing machine with matching program. In most cases, this produces an even better result
with regard to the rolling smoothness (true running, imbalance and weight distribution of the balance
weights) than can be achieved with uncontrolled matching.
Maximum permissible radial runout and lateral runout of the wheels < 0.7 mm. Maximum
permissible radial runout and lateral runout of the wheels with tires < 1.25 mm. Values < 1.50 mm
-ideally approx. 0.5 mm - are desirable.
The mounting pressure (seating pressure) of 58 psi/4.0 bar overpressure must not be exceeded
before both tire beads are evenly seated on the rim flange.

New Tires (Replacements):
•
•
•
•

If new tires are to be mounted or the tires of one axle are to be replaced, tires of the same make,
type and with the same specification code must always be used on each of the two axles.
If tires are replaced on one axle only, the different tread depth from that on the other axle can cause a
noticeable change in the familiar handling.
This is especially the case if new tires are mounted on the rear axle.
This effect decreases with increasing tire mileage.

When replacing a tire on an axle, make sure that the tread depth of the new tire does not differ from that of
the other tire on the same axle by more than 30 %.
Refer to WM 449503 for specific details of the vehicle you are working on.
•
•

>The 2mm specification will be given here.
> If there is none listed then the default is 30%.

Repairs to Tires:
•

•

If a tire is damaged and it cannot be determined with absolute certainty that there is no ply damage
- with all of its consequences - or if the tire was thermally or mechanically overloaded due to a loss
of pressure or other prior damage, we recommend replacement of the tire in question for safety
reasons.
Repairs to "V", "W", "Y", and "ZR" tires are not permissible, as is the use of inner tubes in tubeless
tires.

Tire Aging:
•
•
•

Oct 10, 2023
Page 12 of 13

Tires age due to chemical and physical processes, which can impair their function.
Tires that are stored unused for an extended period harden and become brittle faster than tires that
are in continual use.
Hairline aging cracks can occur on older tires.

On tires in continual use, the kneading action activates the plasticizer in the rubber and thereby
prevents hardening and cracking.
Therefore, attention should be paid not only to the tread depth but also to the age of the tire.
Tires should not be older than 6 years.
The age of the tire can be determined via the DOT code on the sidewall, which indicates the
production date of the tire: e.g. DOT 2201= 22nd week of 2001.
