Further To 1: Fitting The Tyre On The Rim

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Remove rubber residues and dried-on tire paste from the rim, especially from the rim bead and the hump.
Examine rim for damage; remove old balancing weights.
Use the prescribed tire mounting paste (only TIP TOP Universal, order no. 593 0601, 3.5 kg bucket, or Contifix) so that the tire does not turn on the rim the first time the car is driven, thereby counteracting all your careful work. If the tire turns by as little as 20 mm with respect to the rim, this can worsen an optimum balancing result.
Fit tire on the rim. When doing so, it is a good idea -- and even necessary in individual cases -- to fit the tire in a favorable position with respect to the wheel (matching). Compare Controlled and Uncontrolled matching below.

WARNING: High tire seating pressure

Risk of squashing or bruising

→ Use a tire filling cage.

Fill tire. Important: At the latest when the pressure reaches 3.3 bar (max. 4.0 bar in tire filling cage), the tire beads (coming out of the deep bed) must pop over the hump of the rim bead in order to avoid fractures of the bead core. If necessary, interrupt the process and generously coat all necessary surfaces with recommended lubricant (tire mounting paste). Then repeat the process.

IMPORTANT: Damage to the bead core resulting from incorrect tire assembly/disassembly will cause an increase in fluctuations in power (radial/lateral fluctuation in power). This is apparent when you roll the tire on the driving surface.

Uncontrolled matching: Turn the tire on the wheel by 90° or 180° if necessary in order to achieve an acceptable value with regard to rolling smoothness (true running, imbalance and 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 distribution of the balance weights) than can be achieved with uncontrolled matching.
Check the fit of the tire on the rim using the bead centering line.
Set the prescribed tire pressure.
