Yes, I'll second wiswind's comments.

When towing, I'm in the habit of walking around the trailer, and touching the hub on each wheel. It will be warm to the touch - but shouldn't be so hot you can't touch it. And both wheels should be about the same temperature. Differences indicate a brewing problem.

Most trailer tires will dry rot long before the tread is gone. Another hint: Make sure you have a jack and lug wrench that work for the trailer. Your tow vehicle's jack may work; it may not. You want to find out before leaving on a trip. In my experience, Murphy's law dictates that trailer lugs are never the same size as the tow vehicle's lugs. Bring the right wrench.
