I really don't know, never measured them. I traded my 31's for those rims. Guy had them on his YJ. They are a 15x10" rim. I will measure them next time I have a tire off. Shouldn't be too long as I have to put the shocks on when they come in.
Here's another pic:
All those pics were at 3" of lift, yesterday I took it up to 5.5" of lift.
