Tires are the unsung heroes of the trucking world, but they take a beating. Flat tires, uneven wear, and blowouts are all too common. Here's what you need to know about truck trailer tire repair:

Flats: Always carry a spare, and know how to change a tire. Make sure you have the right tools (lug wrench, jack, etc.). Inspect the tire for the cause of the flat (nails, screws, etc.).
