The 235/65r16C is the size and the C on the end signifies they are Euro-Commercial tires which means the tires are appropriate for that vehicle based on the Euro standards. These are passenger tires and not trailer tires, so if you have those tires on a trailer, I definitely recommend replacing them with ST (special trailer) tires that are made differently for trailer use. If that is the case, I have linked the page to all our 16 inch tire options to assist.

That C is not the same as the load rating on a ST tire so it doesn't represent the load capacity. I've attached an article on trailer tires to assist.
