I have a 2011 dodge ram 1500 st. will this work? 17x9 -12mm 4.5bs fuel hostage rims and 33x13.5r17 Iroks. for some reason on the website it says -12 offset and then I click on it and it says just 12 offset. Is this the same thing? I want my tires to stick out a little but I wouldn't think more than an inch or two. also what does hub centric mean? and do I need it? and our bolt pattern is 5x5.5? thanks!
