Maybe a stupid question but one I need answered. Ordered some new wheels for my cruiser and when they arrived, the center hub was too small. Prior to ordering, research "told me" that the OEM wheels for the 80 series cruiser were hub centric. I repeated this to the business where I ordered and got the wrong wheels. Mistake on my part or their part? What is the exact measurement for the axle hub where the wheel mounts? I just went outside and measured 4 1/8 inches on the hub. The wheels they sent me measure 3 1/8 inches. Anyone back me up on this? I'm working overseas and I hope the company I ordered from will pay the return shipping if it was a mistake on their part. Any answers will be greatly appreciated.
