Do I need D tires?

Were not talking off road tires here

As I said before..... A tire with a higher ply rating has benefits beyond the load rating. It is more puncture resistant. I also said that this MAY be important to you.... Many of us DO tow off the pavement. Especially out west. For us it is the "norm" If that is not your "norm", by all means, ignore my advice....Heck, even if it is your norm, you are free to ignore my advice.... It is your money, and your time spent changing tires.... And ultimately, your choice.

Identical tires with a load range increase from “C” to “D” are still physically the same designated size. Without documentation of the addition of a durability factor they are both equal in that respect. The “D” has an increase in ply rating. The materials needed to allow the tire to become stronger and carry more weight via increased inflation pressures in no way (unless documented) increases that tires durability.

Some tire manufacturers will, at some point, add an extra steel belt for puncture resistance. That is strictly at durability item and it has no effect on the tires load capacity.
