CK-30 tread width

[Dachshund]

My wife's brother has a two year old CK-30, and his dad wants to know if it is possible to set the rear tires out wider. Anyone know if this is possible and how to do it? Thanks!

If Ag they can be set out farther, unless already set out.
Turf and R-4's (Industrial) wheels are non-adjustable on that model.
