What 6-bolt (15") rim will bolt to case 1816 3-bolt?..

[1816case]

The 12 hole rims seem hard to find. I see some case 1816 pic's on net that are using 6-hole wheels on their 3-bolt hubs? Wondering what 6-hole rim (bobcat-JD-?)will have the right spacing to use 3 of the 6 holes? I'm putting on 205x70x15 new snow tires. thanks

I used the orange aftermarket wheels made for Bobcat.
