Trailer tires actually don't typically wear out from mileage. Normally it's age that does them in as trailer tires begin to dry rot and become unreliable between 4 and 6 years of age. Instead of trying to track mileage on your tires you'd want to track the year they were made and make a note that at a certain time you will want to have replaced them.

Here's how to tell a tire's age. The DOT number code will be stamped on one side of the tire, near the bead area. This tire identification number will start with the letters DOT, then the next two numbers or letters are the plant code where the tire was manufactured. The last four numbers represent the week and year the tire was built. For example, the numbers 0410 means the fourth week of 2010.
