I see no one has mentioned that a Load Range E has the same load carrying capacity as a Load Range D when inflated to the same pressure. At the LR D pressure, a LR E performs the same - ride, sway, etc.

So you can buy a LR E and use it in place of a LR D.

Actually they have about 18% more capacity when inflated to the same pressure when comparing the 75R15(D) and 75R15(E).

Ah .... Mmmmm ..... Not exactly.

You compared an ST205/75R15 to a ST225/75R15. What is interesting is that the referenced chart doesn't show Load Ranges that Goodyear doesn't make, so you can't actually do an apples to apples comparison for those 2 sizes. (meaning you should be comparing an ST225/75R15 LR E to an ST225/75R15 LR D.) If you look at other charts, you'll see that principle in action.

Actually the rating for a D tire and an E tire is exactly the same at 65 psi within this group of tires. And both D & E are exactly the same as a C when all are at 50 psi. The chart covers them all. Just don't fill more than the sidewall max.
