For more info on Trailer tires go here: http://www.findarticles.com/p/articles/mi_qa3707/is_200209/ai_n9107731 Here is an excerpt from the above article: Adjusting tire pressure can take a few minutes, but it isn't difficult. Having a small compressor at home is a help because the work can be done at your leisure, when the tires are cold. If you must move the trailer to a source of compressed air, the strictest definition of a cold tire is one that has traveled a mile or less, or has cooled for three to four hours. Ambient temperature is also a consideration when setting tire pressures. A 10-degree-rise in ambient temperature equates to a 1 psi change in tire pressure. Thus, if you set your tire pressures on a cool 58-degree F spring day, they will magically rise 2 psi the following day should a weather front come through and pop the temperature up to 78 F Dropping temperature lowers tire pressure the same 1 psi per 10 degrees. So check TP before every trip. Sunlight will also raise the tire pressure A very real variable is sunlight. Tires in the shade versus those sitting in the sun can have definite pressure differences. Testing by a large tire retailer has shown a 3 psi rise in tires left in the sun all day versus those in the shade. This applies to shade versus sun sides of the trailer, moving the trailer from a cool building into the warm sun and so on. Clearly, setting pressures in even morning light and temperatures simplifies the job. I put "Trailer tire ratings" on Google, this is one of about 3.3 million articles.
