Sensitive to tire pressure
I've never had a car this sensitive to tire pressure. Neglected for a few months and was down to 30/32. Pumped back up to 32/36 and the ride is noticeably better. 2000 base with 18" sport design wheels, Pilot Super Sports.

A few months??
This is a sports car brother not a boring people sedan! Everything is sensitive, its inherently the nature of a sports car. Don't hurt its feelings, check tire pressure at least every other gas fill up. You're going to give it a complex. p.s. helps to avoid wheel denting and cuts down on the rattles. |
The sticker on my car calls for 29 in the front for all sizes - is that too low?
|
29 front is not too low. Factory spec is 29F/36R. This will result in understeer so some owners increase the front pressure a few pounds (31-32) and lower the rears a few pounds (34-35) to try and balance out the handling a bit. Ultimately, it depends on what you like.

I'd go with weekly. My 18s are a little wobbly and bent on the insides, but seem to hold pressure fine. I still do it weekly. If you are feeling a bit lazy, go to wal mart and get one of those electronically controlled air pumps with the PSI settings. I like to do completely cold readings, so I've always used a bike pump (good workout) but this little thing has been a joy. It turns off when the pressure has been reached, and is very accurate.
edit: also 32/36 is much better than factory specs. Car rotates like you want it to. |

Bought a "used" base '07 Boxster w/53K miles from a private party. Check tire pressure sensor came on right away. Local Porsche Dealer told me that the tire pressure monitors have a built in obsolence of 5 - 6 years. That's gonna be a $900+ expense that I hadn't planned on!
Also got a groaning in power steering...needs fluid added. How difficult is it to add fluid? |

I was running 29/36 when the tires were first mounted, but quickly bumped up the front a couple pounds as it made the steering a little more responsive. 32 is a little higher than I had, I'll see how it goes. |

Reduced air pressure = softer ride & reduced rattles. Having trouble pinpointing source of a rattle? pump up the air pressure. |
