Good Question
It depends on what style dual wheel adapter you use. There are 2 different styles. One bolts directly to the hub that holds the wheel on the tractor. The problem with that style dual wheel adapter is in the rim spacing between the different rim widths. Wider rims need a wider spacer.
The other style is a ring that goes between the rims. 4 bolts are used to hold the two rims together. You use the same holes in your rim that holds a wheel weight on. I use this style on my 149
This is my 4th year using this set up for plowing. I haven't had any problems with it.
