This is windhchaser's "blog", there's a ton of separate threads. Most of them in foo.

30 psi on a 5 inch tire is like 150 psi in a 25 mm road bike tire. That's extremely overinflated, enough to damage the tire and rim. Not to mention that it's terrible for comfort and handling.
See this article on "hoop stress", needed air pressure is proportional to the tire width. (like Shimagnolo posted above.)
