I dont know what kinda of backspacing they have but one thing when i put them on with my old 31x10.5 they rubbed, now i am running 33's with a 3 in lift and i personally think they look good.they are ....american eagle racing rims 058 to be exact

 

I take that back i believe the backspacing is 3 1/4 if that sounds right but i am pretty sure it is.
