Didn't know the tire pressure was suppose to be in the low 40's
All good points...back to the OP.
Here is a simple list of the the above, plus one or two:
1. Recommended tire PSI range is cold pressure - a tire not driven on for any length of time.
2. Tire operating range is clearly marked on each tire sidewall regardless of brand.
3. Whatever tire pressure you have in it when cold, it will go up - especially with long drives. Try not to exceed max tire pressure when hot...this is listed on the tire sidewall.
4. A normal variance of range cold is from 2-8 psi. That should give you various degrees of different driving feel for you to play with.
5. Anything below 30 is not recommended - unless you have a 4x4 and are on sand.
6. The higher the pressure, the harder the ride and a shortened tire lifespan. The lower the pressure the handling and breaking will suffer.
7. Over-inflated tires can cause crowning (wierd steering over uneven surfaces) as stated above.
8. Check inflation once per month.
9. Tire pressure will be affected by ambient temperature - hot and cold. Adjust according to season.
10. Label inside door is for the tire on the vehicle when delivered. Any custom wheels/tires - disregard the door sticker and go with the manufacturers recommendation or the installers recommendation. Assuming the installer is not an idiot.
11. In some cases - the tire presssure needs to be a bit higher due to sidewall height (custom cases only with a low profile tire). I've had two examples in the past where a mere 3 psi made the difference on whether or not I scraped my front spoiler going into my garage. It will affect ride height.

a little edit on your 10 points...
1. a tire is considered cold if the car has been sitting for more than 3 hours or driven less than 2 miles.
6. the higher the pressure, the more the center of the tire will wear, the lower the pressure, the more the shoulders of the tire will wear. so it's not just high pressure that will shorten the lifespan of a tire.
