General Information On Mounting tires: General

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Information

Always use new rubber valves when changing tires.
The metal valve only needs to be replaced in certain cases. → 443219 REMOVING AND INSTALLING WHEEL ELECTRONICS
When fitting tires, the direction of rotation and the inner and outer sides should be noted.
Only use TIP TOP Universal or Contifix Tire fitting paste.

Before mounting the tires on the wheels, check for damage (cracks, dents etc.) as well as radial and lateral runout. Maximum permissible radial runout and lateral runout of the light alloy wheels = 0.7 mm. Maximum permissible radial runout and lateral runout of the wheel with Tire = 1.25 mm. Values less than 1.0 mm - better around 0.5 mm - are desirable.

When mounting tubeless tires, check the sealing surface of the Tire and the disc wheel for cleanliness and any signs of damage. Bear in mind here that the bead base performs the sealing function on tubeless tires. When mounting the Tire beads, use only the specified Tire mounting pastes. The following can occur if an unsuitable mounting paste is used:

Twisting of the Tire on the rim
Fracture of the bead core during mounting if the seating pressure is too high
Damage to the Tire bead
Damage to the rim surface by aggressive substances.

If Contifix is used, apply sparingly to the Tire beads (due to risk of the Tire turning on the wheel). If possible, the vehicle should not be driven for 24 hours after Tire mounting or matching.

Information

Customers should be informed that the full performance of new or newly mounted tires is achieved only after a distance of 100 to 200 km (60 to 120 miles) has been driven. Extreme driving manoeuvres (acceleration, braking) should be avoided.
The absolute limit on how far the Tire can turn on the wheel must be regarded as 20 mm. Furthermore, this will worsen the result of optimum balancing.
Mark the relative positions of the Tire and wheel for reference.

In order to optimise rolling smoothness, it is a good idea - and necessary in individual cases - to mount the Tire in a favourable position with respect to the wheel (matching).
