Most likely me being a hypochondriac - BUT, does anyone else have a "ridge" forming in the middle of the front tyre? I can just feel it running my finger over it (from left to right)
Hope it's nothing alarming. Can't recall having experienced this on any bike before..
How many miles do you have on the tires? I don't have the 'line' down the center (I probably did when it was new) although I do feel a slight ridge where the line was directly in the center. Seems normal to me. I know Chromes are particular on the tire pressure. I believe recommended is 40 lbs. I use 37-38 on mine and it feels good for the riding I do.
Not a stupid question at all, and I did. However the line is ever so slightly raised, or rather you can feel it like a subtle seam. If it was something stuck under the mudguard it would have worn a groove I reckon.
