In tire-talk there are two basic types of construction that tires of all sorts use as their foundation. These types include bias and radial tires and apply to mud, all-terrain and street tires as well as trailer tires. Each type of tire construction has its own unique set of characteristics that affect its performance. Most motorists believe that radial tires are better for their cars than bias tires. Does this also mean you should buy these types of tires for your trailer?.
Differences Between Radial and Bias Tires
Radials have plies that run perpendicular across the tire and belts, running below the tread around the tire’s circumference.
Bias ply tires have their plies running diagonal from one bead to the other bead at about a 30 degree angle.
What Tire Ply is Better for Trailers?
The type of tire you choose depends on the way your trailer handles. Before choosing tires consider your trailer’s handling as well as the manufacturer’s recommended tire type. Bias tires have stiffer sidewalls; this can help stabilize trailers that tend to sway. Bias tires are also preferred for heavier loads. Radials, on the other hand, are known for their superior tread wear. They last on average 40,000 miles where bias tires are usually only good for 12,000 miles. Radial tires are also less prone to the development of flat spots and trailer owners who park their trailers in the same position for weeks at a time should go with this option. Radials also tend to run cooler on longer trips.
Based on the above, radials might be worth the added cost if you put lots of miles on your trailer every year, leave it parked for extended periods of time, and are looking for improved traction on or off-road.

It is important that each of your trailer’s tires are the same size, type, and construction. It is especially important not to mix bias and radial tires.
