At what negative tire pressure can a Porsche not be driven?
1 Answers
Generally speaking, a Porsche should not be driven if the tire pressure is below 1.7 bar. Due to thermal expansion and contraction, tire pressure will increase by approximately 0.1 bar to 0.2 bar after the vehicle warms up. If the owner finds that the tire pressure is still below 1.7 bar after the vehicle has warmed up, they should promptly stop and turn off the engine, then use an air pump to inflate the tires to the appropriate pressure before continuing to drive. If an air pump is not available, the only options are to call the insurance company for roadside assistance or contact a nearby 4S store to send help. If the tire pressure is too low, it can cause wave-like deformation of the tires during high-speed driving, which accelerates tire aging and increases the risk of a blowout.
