What is the tire pressure for a 1995 Toyota Corolla?

I just checked the manual in my 95 Corolla and it indicates 30 psi for most tires. I was checking b/c I just got new tires and suddenly my car was pulling strongly to one side. But I checked pressures and the new tires were inflated in the high 30s. I let some air out and my car doesn't seem to be pulling so much.
