Tires are rarely perfect. Don't worry about it.
You shouldn't do that at all. It's an easy mistake and not something that most people would ever check for or notice. If it isn't seated, to give a concentric ring, try this - inflate slightly (maybe 10psi) then find where the sidewall line dips below rim level. At that spot, try to roll the tire off the rim away from you. Push with the thumbs. The line should pop up above the rim. I always check for this on both sides when mounting a tire.JonathanGennick said:If the problem is all in how I mounted the tire, I'm going to feel rather foolish.
