Tires: Testing and Inspection

Wheel Rims And Tires

Tire condition/Tire pressure

WARNING:
Danger of injury and damage to property as a resuit of modified handling behavior if tires are used which do not correspond to Porsche-specific requirements.
- The stated air pressures are minimum pressures and must never be fallen below, since in addition to the unfavorable driving performance, this would bring about a risk of serious tire damage.
- Besides a check on air pressure, a visual check must be made for sufficient tread depth, foreign bodies, punctures, cuts, cracks and bulges in the sidewall (ply breakage).

NOTE: Valve caps protect the valve from dust and dirt and therefore from leaks. Always screw caps tight and replace any missing caps.

Overview Of Tires And Wheels (Series)







- The chart of tires and wheels for summer and winter should be taken from Technical Information (TI) Group 4.
- When replacing summer tires, pay close attention to the tire specification number! The specification characters N1, N2, N3 or NO distinguish the summer tires specially authorised by Porsche from other models of the same tire type and size.

NOTE: When mounting the wheel on the vehicle, observe the mounting specifications of the wheel bolts.

Notes On Mounting Tires
- When fitting tires, the direction of rotation and the inner and outer sides should be noted.
