I'm looking at getting HE878 wheels for my 2012 F150 Lariat in 18x9. I've tried reading up on what offset is and have a general idea of how it works but I just don't know how much these would stick out. Does anyone have an estimate on how much these would stick out? Any advice in general? Heres the link where to find them (page 4). They have a -12 offset. Helo HE878
