If required, move tire on wheel by 90锟斤拷 or 120锟斤拷 degrees to find acceptable values regarding out of round conditions, imbalance, and wheel balancing
weight application.
Controlled matching:
Use balancing equipment with matching program capability. Values can be optimized.
Maximum permissible axial and lateral run out of wheels <=0.7 mm.
Maximum permissible axial and lateral run out of tire and wheel assembly <=1.25 mm (desired value <= 1.0 mm).
When mounting tires do not exceed inflation pressure of 4.0 bar while seating tire beads.
When new tires are mounted on one axle always use a matched set from the same tire manufacturer with the same "N" designation. The handling
characteristics of the vehicle may be affected by differing tread depths between front and rear axle tire sets. This effect is especially true when the
rear tire set has been replaced. Use caution during break in of tires.
When handling tire complaints and tire damage is determined, the tire should be replaced. The tire should also be replaced if you are uncertain
about cord damage or if the appearance of overheating makes the tire suspect in any manner.
When replacing a single tire on one axle, the difference in tread depth on the axle may not exceed 30%.
Repairs on ZR tires and use of tire tubes are not allowed.
Other Tire Handling Notes:
The chemical and physical properties of a tire may be affected by long storage time, and the rubber compound may harden over time. Tires which
are in constant use or motion will maintain a pliable compound and delay the hardening process.
Therefore, the concern should not only be tread depth but the age of the tire as well. Tires should not be older than six years from date of
manufacture (includes spare tire).
The tire age can be determined from the DOT stamp on the outside of the tire sidewall. For example, "DOT..067" week 6, 1997.
Generally, tires should be stored in a cool, dry and well ventilated area. Keep away from sunlight. Avoid contact with fuels, grease, oils and other
chemicals.
Mounted wheel sets may be stacked if required. It is recommended to increase tire pressure by about 0.4 bar.
Tires that are not mounted should be stored in a vertical position. We recommend rotating the tires every two (2) weeks to avoid flat spotting. If
tires are stored in a horizontal manner they may deform and be difficult to install.
The original Porsche tire storage system, part number, 000 044 000 22 is available from the parts department to store complete wheel/tire sets.

Clutch Pedal Noise
Vehicle Type:
Boxster/Boxster S
Model Year:
As of 1997 (V)
Concern:
Noises during actuation of the clutch pedal.
Information:
When operating the clutch pedal, various types of noises may occur. When diagnosing the noise, leave the drivers door open. This will allow you to
detect any noises that may be external in nature.
Work Procedure:
Scratching or scraping noise.
