Yup that ring the split goes to the edge
Not just the split in the smaller locking part
One of the 2 or 2.5 tons I got have some funny rim like that but I don’t use it
It’s sinking into the dirt slowly
I like the three part one because slow and steady gets them apart without much grunting
Just massage it and it will go without much effort but it takes a while to work it all around the bead several trips just working it slowly
