You are correct. My mistake. Went back and looked at an OEM spare and it is definitely a D. Must’ve been thinking about a set of C’s on an old Bronco of mine.They came with Load: D tires but unfortunately BFG don’t make them available other than to Ford. I don’t recall ever seeing them available retail-wise other than E for the OEM Metric sized site. Oddly enough I do see C now.
I’m on my 5th set of KO’s on this truck and have had 35D’s, 35E’s,and 37D’s. The latest set of metric C’s is my favorite yet for ride quality, particularly at higher speeds.
