Question:

Can you provide the outside diameter at the base of the hub 8-258BTUC1, where the back of the wheel meets the flange? I have tried searching for the answer before asking but cannot find it. I have all the other info I need and once I know this, I should be able to place my order. Thanks Joe

Thank you sir but I already had that dimension from your website. I was able to find everything except what I am asking for. I would attach a picture for clarification like you did, but your communication system won't allow it. So I will attempt to describe again. I need the outside diameter of the hub that houses the bearings. My wheel hub bore is 83 mm. I want to figure out how much gap there will be, or if the wheel bore on my wheels is too small to slide over. I am guessing it is fine but before I purchase them I want to make sure. My wheels are lug centric, so as long as the wheel hub bore is large enough to slide onto the hub, then I should be good to go. Hope that clears it up a bit more. It would've been nice if I could attach a pic. Joe

@OutsideH Sorry for the confusion. The hub bore size is 2-1/2" or roughly 63mm so there is plenty of room with your wheels having a 83mm hub bore opening.
