What is the difference between 75r and 75d tires?
The difference between them is the tire’s type of construction. The ST205/75D14 tire is a bias ply type with a Load Range D rating. The ST205/75R14 tire is radial type that will typically run cooler than a bias ply and this means it will be likely to last longer.
What does D mean in tire size?
D is for tires built with diagonal (crisscrossed) plies, called bias-constructed tires. They are also called conventional, x-ply, or cross-ply tires. Some motorcycle and trailer tires still use this internal construction.

Can I mix R and D tires?
Expert Reply: It’s fine to use a radial-type tire as a spare (a tire with “r” in its size code) with a trailer that has Bias ply “d” tires but for a short distance in the event of a flat tire. But mixing tires is not recommended for everyday use because their internal construction is different.
Which is better D or R tires?
Radial tires have a wider footprint, which spreads out tread wear and also adds to the life of the tire. Radial tires are more resistant to punctures. Radial tires provide better fuel economy because they have less rolling resistance. Modern ST radial tires are reinforced and designed for heavy loads.
