Trailer tires come in a variety of types, including radial, bias-ply, and steel-belted. Radial tires offer the best combination of durability, traction, and fuel efficiency, while bias-ply tires are suitable for lighter loads. Steel-belted tires provide the highest level of puncture resistance.

The correct trailer tire size depends on several factors, including the size and weight of your trailer, the type of terrain you'll be driving on, and the speed at which you'll be traveling. You can usually find the recommended tire size in your trailer's owner's manual or on the sidewall of your current tires.

The lifespan of trailer tires varies depending on the type of tire, the driving conditions, and the amount of use. In general, you should inspect your tires regularly for signs of wear and tear, such as cracks, bulges, or uneven wear. You should also have your tires inspected by a professional at least once a year.

To maintain trailer tires, you should check the tire pressure regularly, rotate the tires every 5,000 to 8,000 miles, and have them balanced every year. You should also avoid overloading your trailer and driving on rough roads. If you notice any signs of damage, have your tires inspected by a professional as soon as possible.
