22X9.5 on BD 01' Blazer, what offset to run?

Need to get some ideas of what offset you guys are running on 98 and up two-door blazers with a 22X9.5" wheel with a 30 series tire. I want to get the wheels before it goes in for the BD, so that it is BD to lay on 22's from day one.

Thanks in advance for the help...Erik

bump... how many milimeters is that? And would it be positive or negative?
