Default Wheel size decipher???

Can anyone explain the wheel dimensions as far as the end letter code goes?

The sticker inside my door jam has info on the tire size, psi, and rim size.
what I don't know is what the letter at the end stands for.
For example...

My tire size is 285/75/16 C
My rim size is 7.50 X 16 J

I have a trailer that has rim size 5.50 X 16 F

What are these letters on the ends of the sizes? C, J, F ???

On a truck tire, labeled LT, the letter following the tire size is the load rating and pertains to the number of plys.
On other tires, the load range consists of two numeric characters followed by the speed rating.
In addition, there is NO "C" speed rating.

f5,

As I read him he's asking what the letter means on the rim, not the tire.

His quote:
What are these letters on the ends of the sizes? C, J, F ???
And I believe the rim is the same rating.....
