Radial trailer tires are designed to reduce trailer sway, support heavy loads, run cooler, and have longer tread wear. They achieve this through rubber-coated steel cables running at a 90-degree angle to the travel direction and more steel belts at the crown. Radial trailer tires are well-suited for carrying heavy loads over long distances and more fuel-efficient during extended hauls. They also resist flat spots when parked for extended periods. Trailer tires are designed for lower rolling resistance and better grip during braking, making them ideal for towing heavy loads.
