You can (hopefully) see that the tire is being slightly lighted off the rim in the area of the valve. I've measured the tire itself in the area of the valve and the small cylindrical protrusion in the casing is 9mm in diameter. I have an 8.3mm hole in my rim. Is the solution as simple as opening up the hole in the rim to clear that protrusion? Or do I just leave this as-is?
