2013 Porsche 911: Choosing a Tire Pressure for Everyday Driving

May 14, 2013

As you can see, there's not much sidewall to the tires on our Porsche 911. A set of 20-inch wheels doesn't leave much room for such extravagances. The result is a slightly jarring ride depending on what you consider jarring.

Personally, I think our 911 rides exceptionally well given its combination of paper thin sidewall and firm suspension. It's an easy everyday driver, even on the beat-up, concrete highways here in Southern California.

Of course, not everybody agrees and Porsche knows that. There's apparently enough disagreement that the company even provides two sets of tire pressures. There are the standard settings on the door jamb and the "comfort" settings in the owner's manual. And even with those, there are "part load" and "full load" settings.

Needless to say, Porsche's engineers have gone to great lengths to dial in the correct pressures for the various situations you might encounter in the 911. It's as much art as it is science, requiring thousands of hours of testing and research. With that in mind, the next time you see a new Porsche 911 with aftermarket tires and wheels, don't listen to the owner if he or she says it rides like a truck.
