What does load rating D mean?
Load range D tires only provide more capacity and a harsher ride if they are inflated to the higher-rated design pressure. A truck with load range D tires can be run with the lower air pressure for a better ride and inflated to full pressure when the load capacity is needed.
What’s the difference between R&D on a trailer tire?
The difference between the two trailer tire sizes is that the letter D in the first size you listed ST205/75D15 stands for bias ply and the letter R in the tire size that they put on your vehicle stands for radial.

L: Only apply these tires to off-road trucks that will not exceed 75 mph.
What is D rated trailer tire?
– Due to the tire’s design, the ride might be rougher. – Bias trailer tires tend to have a shorter shelf life than radial trailer tires. Therefore, these tires aren’t a great option for regular trailer users. – Along the same lines, they wear down quicker due to the rugged design meant for rougher roads.
