I got fed up with hawthorn punctures and ordered some Armadillo tires
from Wiggle ("Specialized Fast Trak LK Armadillo Elite Folding Tyre" -
£25 each). These were sized at 26x2.0, while the old tires were
26x1.95. The Wiggle salespeople said that would be fine as long as the
tire fit between the brake calipers. It fit, though the tire is
noticeably larger, and takes more air than the old one.
On the first ride with the new tires, the rear one got a flat after
about 45 min of riding. It was a strange sort of flat - a vertical
tear in the unpatchable neck of the inner tube. This was an old
patched-up tube, so I replaced it with a new one. Same thing happened
45 min later. And again after that! Three inner tubes dead in the same
way.
I cannot feel or see any burrs in the rim hole. Running the neck of an
inner tube roughly through the hole does not abrade it. Anyway,
everything was fine with that wheel before the Armadillos.
And the front tire, also with a new Armadillo, has been fine.
Can anyone suggest what might be wrong? Wiggle merely supposed that
the tube might not be fitting squarely. I suppose the next step is to
put the old tire back on and see what happens.
