2.2 inch wheels and tires?

Has anyone tried 1/10th scale truck size wheels and tires on their Maxx before? Im looking for something about the size of my Panther KLPs, but with a more off road oriented tread pattern. I tried the wheels off my brothers Stampede, and they were really close to fitting around the knuckles. I know Ill have to make a 12mm hex fit on my Emaxx, but that wont be a problem. I was wondering if anyone knows of any slightly larger inner diameter stadium truck wheels that are available for traxxas vehicles ( meaning they have a 12mm hex). Or any larger ID 1/10th ST wheels for that matter, Ill just have to figure out a different way to mount them.
Thanks for any help.
