Are the Wrangler Duratracs the only load range C tires to fit stock Rubicons?

Should be getting my W2 by the end of the month and hopefully new tires by the middle of February. In 245/75 R16, are the Duratracs really the only load range C tires available? According to Tire Rack, they are.

What is the real science behind the difference between a C and D class tire? I get it, “my butt dyno says.” The C is like a cloud and D class is like a brick. But is there any more to it? I obviously believe there is a difference, what is it? Is it truly measurable? Is it tangible?

The sidewall stiffness. A good part of your suspension is in the tire sidewall. This is why an overinflated tire rides like crap. It prevents the sidewall from flexing. This is every bit as important on road as off. I have seen that the tire provides 25% of your suspension. Obviously a tire doesn't flex 3" over a rut, but it does absorb the road shock so that the springs only need to move 1". As far as a softness meter shocks are #1. Tires #2. Springs #3. I think every vehicle is different, but a Wrangler (where you are basically sitting directly above the tire) is highly effected by tire stiffness.
