I just bought a pair of 700x23 Armadillos from a LBS on Monday. I noticed on the front tire that the bead line seam in one particular area falls below the lip of the rim, while the rest of the tire has the bead line seam just above the lip of the rim where it belongs. Consequently, the tire in this location sort of dips when it rolls, giving a "wobbly" ride. The rim appears true and to test that out, I took out the tube, spun the tire around so that this funny spot was now by the stem hole (used to be opposite the stem hole), and then put the tube and tire back on. The tire still dips funny in that same spot, so at least I know the rim's true. Did I just get a bad tire? Have you ever seen tires like this? Should I take it back to the LBS and hopefully they'll be cool about swapping it out?

The 1st pic is of the normal bead line, 2nd is it starting to dip, and the 3rd it the bead line going down below the rim's edge.

It's funny, though. When I take the entire tire off and look at the bead seam line, it doesn't look shorter in that one area. :( So I don't know what the deal is. I can't take the tire back if it isn't even evident off the rim that there's something wrong with it. Maybe I just don't know how to seat the tire on the rim well...but at that same spot every time?

I've seen tires do that, I don't remember changing them out or anything, just trying to get the bead to seat more evenly and riding them.

are you getting the tube seat correctly. I think that may be your problem.

No. I don't think it's the tube. I took the tube out and rotated the tire around and the spot follows where that location is on the tire. Think it's just a tire defect thing. Seems so unnoticeable, though, when the tire's off the rim. Hopefully it will just work itself to seat evenly over time with lots of cornering and riding. :o

Did you pump it up to full pressure? I've had Armadillos sit low in spots until the pressure gets pretty high. The bead then pops into place.

Pump them up full and go ride around a while and see if the tire doesn't seat better. It's not likely to blowout on you since the bead would have to get past the hook first.

--- Does your bicycle have hook-bead rims or straight sided rims?
