Weird exploding tires

Hello All

Thanks to everyone for all the help. I believe I now have the answer. It's a
problem with the rim.

I went back to the bike shop. Without even looking at it, a technician there
said it was the rim. He was so sure, he said he would not even try mounting
the tire for me for fear it would blow out in the shop. Skeptical, since the
last tire held fine, I had them give me a new set of tires - a different
brand and configuration - 90 lb tires instead of 105, a rough bead and not
Kevlar. The front seated nice and tight into the rim, but I could not get
the rear one to sit low in the rim once it was pressured up - no matter how
much I fiddled with it. After gradually bringing it up to 90 lbs (I actually
used earplugs and left both rims outside) -- 20 minutes later ... KABOOM!!!
Tube number three bits the dust.


SOOOOO... now I have to figure out what to do. My front rim (a different
brand and age) is steel. No point in getting one alloy rim, so unless I can
still find a cheap steel one, I guess it's time to replace both rim, now
that I just repacked both hubs :O( I don't even know what size rims to put
on this. I have a road bike with 700s on it. Maybe I'll try those rims on
and seeing how it lines up with the brakes. A lot of work for a 30 year
old, $79 10-speed.

Thanks again everyone.

Well, now we know for sure. Reports like this do teach us things.

I wouldn't use steel rims, unless I lived in someplace as dry as Nevada.
With steel rims, the braking in the wet scary-dismal. I know that by
experience.

It may be worth the time to troll the thrift stores and garage sales for
a while. You might be able to find a very inexpensive used bike with
decent aluminum-rimmed wheels.

All rims are used, as soon as they've been on a bike once. Some are
just more used than others. I've seen numerous $20 road bikes with
aluminum 27" rims showing little or no wear on bikes at Goodwill in
the past several months. Since I have no need for another road or
touring bike right now, I have been passing them up.

Wait a minute. I thought you had originally said that the front and
rear rims were the same; had the rear perhaps been swapped out at some
point? What you're describing here sounds very much as though the
rear was a 700C rim with a 27" tire on it; that's consistent with the
results you describe.

It's certainly how I got my 'car drove into me at speed' story. Mind
you, I wan't wearing a helmet, so I'm probably no longer with you to
post this... ;-)

Actually, I had forgotten that over the years, I had replaced each of the
rims at different times. The back one is stamped prominently in the steel -
"RIGIDA 18*630 (27 1 1/4) 32 92 21 STEEL MADE IN FRANCE"

The scary thing is there is no way, looking at this rim, that you would
suspect any problem. Anyone want to buy a used rim :O)

Don't think anyone still is watching this thread... but just in case anyone
ever Googles it ....

I ended up getting a replacement steel rim 27 1/4 for $30. Just couldn't
justify getting two new alloys for this old bike. 95 pound tube has been on
for at least a week and holds just fine!!!!! So it looks like it was the
rim - just couldn't hold a tire any longer.

Thanks again everyone.
