What’s the difference between 205 75R15 and 205 75D15?
Expert Reply: The difference between a D15 tire and an R15 tire is the construction. The D denotes that it’s a bias tire and the R is for a radial tire. D range tires are a bit more heavy duty than C range tires and are more suitable for larger open trailers or enclosed cargo trailers.D tires are typically rated for a higher load capacity, making them ideal for heavy-duty trailers that carry substantial weight. On the other hand, R tires are generally designed for lighter loads and provide a smoother ride, which can be beneficial for recreational trailers.At the same time, R/T tires are much more highway-friendly than mud-terrain tires, and have lower noise levels and improved ride quality. All this, without very little compromise in performance.If your travels involve rough or unpaved roads, D tires provide enhanced durability and grip, making them a better choice. For primarily highway driving, R tires can offer a quieter, more comfortable experience. Additionally, think about the weather conditions you typically encounter.
What’s the difference between 75R15 and 75D15 tires?
The D in 75D15 stands for diagonal or bias ply, indicating that the tire’s internal fabric layers are diagonally arranged, while the R in 75R15 stands for radial, meaning that the tire’s internal fabric layers are arranged radially from the center. The letter R means the tyre is a radial construction. Almost all new car tyres are radials.
What does the D stand for in 205 75D15?
The D is the designation for the internal construction of the tire. The D stands for diagonal or bias ply construction. That means the tire body plies inside the tire will crisscross. The 15 is the wheel diameter in inches and the C after the tire size will designate the load range. For example, a C load range indicates that a tire is equivalent to a 6-ply construction tire.
