I am looking at buying 17x9 raceline Raptor wheels for my 2013 jeep unlimited. They are telling me they are either Zero offset or 5.0 inch backspacing. Everything I read is I shouldn't have more that 4.5 backspacing or -12 offset. I'm looking at putting these wheels with 285 70r 17 DuraTrac I'm nervous about ordering these. I'm new to this and I really appreciate any knowledge.
