Mine are the split rims . we also brought my sons 48 two ton home yesterday so we can work on them both and he has locking rings on it. His 48 has 700.-20s my 65 has 7.50-20s They appear to look the same. I will check when I get home from work today and try to get and post pics. Is thier one pic hosting site easier to use than the rest. Thanks Lou. H.
