You know the routine when it comes to tires on your car or truck. Check the air pressure. Rotate them. Test for proper alignment. Monitor the tread. These are all routine tasks that can ensure your tires are performing at the best of their abilities, as well as a means of catching small problems before they become big ones. But there's another type of tire that we're all familiar with -the trailer tire. And just because they're trailer tires doesn't mean that they too don't need proper TLC.
