Anyone know if these tires will mount on a 9 inch wheel. I just picked up a set of 20x9 BMF wheels and would like to get these tires in a 33 12.50 20. I spoke to 2 people at Atturo and one said yes it will mount on a 9 inch wheel and the other said it has to be at least a 9.5 inch wheel. Anyone have these mounted on a 9 inch wheel??
