I think that we are looking at 2 different things on the chart you referenced.
The "C" tire would have only a 1760# rating at 35 psi. Way too little IMO. You will have to inflate it to 50 psi to get a 2150# rating. Should be OK. But I'd do the "D" at 60 or 65 psi w/2380 - 2540# rating.

I'm still thinking about the Maxxis "E" 225 75R15. From other posts, this tire runs smooth with little or no excess bounce.
