There is probably not a single number good for all tires, but 36-40 is a decent range. The heavier the car the higher the pressure. The key is to make sure they don't lose pressure.
My new Jeep has tire pressure monitors, its pretty cool. I need to get some wireless ones for my car trailer. When I loaded up the 6.3 last weekend I had a low tire but it didn't show until I had a 4000lb car on it.
