proper psi for 225/40/18

[mrjaydeeone]

I was looking at my car this morning and noticed that my left front rim was just about on the floor. Someone let the air out of my tire. My gurlfriend noticed that the air cap was missing too. Maybe it was a punk kid that stole the chrome air cap or what ever.
anywas tried to see what the other tires had so I would know what to put in this one and the right rear had 17psi the left front had 17psi and the left rear had 37psi. I have had these tires since April of 01, and haven't checked the air in them or anything. The left front tire was replaced 2x already due to blow outs from potholes, but anyways. What should I have in these tires.
Another thing I was driving on Thursday and the car was pulling ridiculously to the right. Thought I needed an alignment, was trying to figure out what the hell I hit to cause that. After I put air in the front tire the car starting to drive straight again. I put 30psi in each tire.
what should I have. Don't know if this matters or not, but the tires are Yokohama Parada Spec II. Members with those tires how much air you got in them?

You should run 33psi in front and 30 psi in the rear.

Our cars are supposed to be run stock with 32psi up front and 29 psi in the rear. The best option is to run somewhat similar to that. The Eclipse runs 33psi and 30psi, respectively at stock.

I gotcha. I just wasnt sure if it depended on what we run stock or if it depended on the tire size

When I had my rims put on, both the front and back had more than 40 psi!! I'm lucky my tires didn't blow up, but they were making weird sounds...

Now they are all at around 30 and it sounds OK.

i find my tires are squishy feeling under 39psi. i feel them up to 40psi, and i feel dangerous, but i've been doing that for as long as i've had low pros, and the tires are stiffer in turns for me.

Now my tires are at around 32-34 psi, but somehow they look underinflated, especially the front ones.
