Hub centric spacers? Do I need them

Okay, so I bought 1.25" aluminum spacers, that are not hub centric. Should they be returned? I didn't know jeep did this until after I bought them. Is my 05 wk hub centric? I have Bilstein shocks and struts delivering tmrw, install is Thursday along with RC 2" lift. I planned to take it for 265/70 tires on Thursday, after lift and shocks are done tmrw. I sort of stumbled across hub centric today, not realizing until now that this may pose a problem for me. So...

Do I need hub centric spacers? Or is that only a wrangler thing?



Thanks guys
