Mounting tyres
- Risk of squashing or bruising
→ Use a tyre filling cage.
- After mounting the tubeless tyres, inflate them without valve insert to max. 4.0 bar (58 psi) gauge pressure to ensure they are seated properly on the rim. By the time the pressure reaches 4.0 bar (58 psi), at the latest, the tyre beads must pop out of the deep bed and over the hump of the rim bead in order to avoid fractures of the bead core. Interrupt the process if necessary and generously coat all necessary surfaces with sliding compound (tyre mounting paste) again. Then repeat the process. Screw in the valve insert and set the specified tyre pressure.
If new tyres are to be mounted or the tyres of one axle are to be replaced, tyres of the same make and with the same specification code must always be used on each of the two axles. If tyres are replaced on one axle only, the different tread depth in relation to the other axle can cause a noticeable change in the handling the driver has become accustomed to. This is especially true if new tyres are mounted on the rear axle. This effect decreases with increasing tyre mileage.
Information
- If a tyre is damaged and it cannot be determined with absolute certainty that there is no ply damage - with all of its consequences - or if the tyre was thermally or mechanically overloaded due to a loss of pressure or other prior damage, we recommend replacement of the tyre in question for safety reasons .
- When replacing a tyre on an axle, make sure that the tread depth of the new tyre does not differ from that of the other tyre by more than 30 % .
- Repairs to the tyres are not permitted nor is the use of inner tubes in tubeless tyres .
- When replacing summer tyres, pay close attention to the tyre specification number .
The overview of summer and winter tyres is included in Technical Information (TI), Group 4. When replacing summer tyres, pay close attention to the tyre specification number for the same make of tyre. The specification characters (for example N0) distinguish the summer tyres specially authorized by Porsche from other models of the same tyre type and size.
