I took my bike all apart and cleaned everything this weekend, and replace a slowly leaking tube. Now that I have everything put back together, the tire doesn't seem to be seated right. As best I can tell (using the brake as a guide), the rim is round. However, the tire is probably off by 1/4" from one side to another. I deflated the tube and re-inflated it after checking to make sure the bead appeared to be seated properly.
I don't ride this bike much and when I do, it's usually during snowy conditions on poorly maintained roads, so it's possible it has been this way since I put it on a year ago and I just have a defective tire.
Is there something I could have done wrong during the re-installation that could have caused this? I'm racking my brain trying to figure this out and I got nothing. I thought about taking the tire all the way back on and rotating it on the rim or seeing if there's some type of defect.
