Hey Benny, in a Cooper branded tire, it's called a SRM II

In a Mastercraft brand (the same tire made by Cooper) it's a Courser R/D. You have to scroll the page to see the specs at the bottom.

If you notice the specs/sizing are identical for both tires, it's because Cooper makes both, but just puts 2 different names on them, even though they are the same tire. A lot of the time, you might be able to get a better price deal on the Mastercrafts. Hope this helps you.
