The "R" and "D" on trailer tires stand for Radial and Diagonal (also known as Bias), respectively, which are two different types of tire construction. Radial tires have steel belts running at a 90-degree angle of the tire's tread center line, providing benefits like better heat dissipation and longer tread life, while Diagonal (Bias) tires have belts running from one bead to the other at a 30-45 degree angle, making them more robust and resistant to damage.
