The main difference between ST205 75R15 and ST205 75D15 tires lies in the construction of the tire, specifically in the "R" and "D" designation. "R" stands for Radial construction, meaning the tire's internal ply cords are oriented in a radial direction, from one bead over to the other, while "D" stands for Diagonal (or bias) construction, meaning the ply cords are at an angle or bias to the direction of travel.
