Spider trac. On a 3 bolt rim?

[King Trikester]

178101178089 I found a set of dick ceepek spider trac's they are in really good shape no cracks that I could see. I was told the rims are from an early 80's 250r, but they only have 3 bolts? Did 250r's have 3 bolts, it looks like it would bolt right on to my 83 dx.

yes. 1981 models had 3 bolt 3x100 hubs.

82 had 4x130 hubs
and 83-up had 4x110 hubs

Ok thank you, so I guess I have an 81 250r frame. One more question is that the same bolt pattern as the 83 225dx? I am going to try them out on the dx, they look like they will do well in the snow
