Knowing we have several Europeans on this forum I am hoping someone will have a suggestion on where to look for my answer.
I suspect there is a standard or regulation regarding the bolt pattern dimensions for agricultural tyres and wheels. Are they different than over the road wheel dimensions? I have been looking for CE references but so far have been unable to find any mention of it even though my European supplier has a different dimension than my American suppliers.
Of course then I need to see if that same standard is recognized in Brazil and Australia.
