The past years' rules would normally state that you can't use wheels of the sort, they supplied brackets for smaller wheels or your bumper height had to be quite low. People just didn't really use them because the disadvantages outweighed the advantages. This year, they are a huge asset. I am also quite sure that the only 10" wheels readily available through sites such as Andymark are 10" Mechanums (which are not desired to go over the bump) and 10" Pneumatic wheels.
I hope that helped.
