Default Proper tire pressure

Hello all. The tire pressure on the door of my 02 SSEI says I want 30lbs in my tires. Does everyone keep them at the same pressure, 30lbs to get the best ride?

Now, is this with stock tires? Or will the pressure change with other tires? The max psi on the Pirelli'* on mine say 44 psi, so I went with 37. Really, if I go less than that, the tire wears unevenly.

Max press and recommend are 2 diffenrt things. You should run the press listed on the door sticker. Max press is just that- the max press you can safely run w/o the tire self destructing. On my Pilots 35 was too much I measured in 2 weeks the center was wearing fast. Dropped to allmost rec press and the rapid wear stopped.
You say they wear funny- how?

The outsides wear faster with anything less than 35, really, but I don't run the max. 44 is max, I run 37. I haven't seen much wear, mind you, Ihaven't had the car that long, but the rubber is blacker on the outside.

They sell gauges for tread dept or take a tooth pick and mark it new and check later to be sure. Also check the air press gauge. Alot of gas station ones are WAY off. The cheap'es are not much better and can show wrong readings if you hold them @ a angle. The one that came in the bag of my '00 is close. I use a digtal one. @ allmost $200 ea for the tires I'm not taking chances.
