I can not get tires to stay on my Weinmann rims

Hi all,

I found that old thread using the highly recommended UTFS button... So I originaly wrote that story in GA2G's list of anti puncture tyres the other day, but it turned out that this had nothing to do with the tyre quality, so I repost myself here...

Hi all,

Maybe this is not the right thread to post this... GA2G, let me know if you would like me to move that somewhere else... (so please do not quote me...)
So I have on my Mercian touring bike these tyres fitted...
http://www.roadcyclinguk.com/news/article/mps/uan/2811
Continental Ultra GatorSkin with "DuraSkin + K" (Kevlar or whatever that means)
They are 27X1 1/4, fitted on Weimann aluminium rims from the late 70s (in good condition). I rarely use the same bike every day, and I often use this one when it is raining as it is my only bike with mudgards... but the bike never "sleeps" outside, and the metal inner structure of the tyre was not rusted.
So I'd say these tyres, purchased last march, have less than 300 miles. I never exceed the recommended pressure (102 psi) and even give a bit of tolerance (90-95 psi), as I like the confortable feel of that touring bike...
This morning on my way to work, just after Camberwell, the front tyre suddenly developped a massive "bump" on the l.h.s., I did not have time to stop, by the time the bump went thru the brake calipers, it cut the inner tube and exploded in a huge bang. The explosion even broke the mudgard!
I managed to repair "how I could" using my toe straps and the cardboard of my spare inner tube box, I had to remove the brake and mudgard to have enough clearance for the repaired tyre to go thru. I could cycle to work in Putney, but was a bit late, I had to re-strap and and re-inflate twice before I got it right...
I think there must be a fault in the tyre, as I can't see any reason for it to explode (no cuts, the brake pads were not rubbing on the walls,...) and I expect the garantee to work, and Continental to replace the tyre for free (I hope) I remember this happened to someone on the Vintage Jersey Ride (Part 01), but it was cheaper tyres, made in SriLanka, not the "Noble" "Handmade In Germany" Continental tyres...
I'll let you know what they tell me in Putney cycle at lunch time (where I purchased the tyres from)

Putney cycle gave me a new tyre for free.
I went there today to show them the mounted tyre, as there is some tiny variations of paralellism between the edge of the tyre and the rim and I wanted to know if that could lead to another explosion, and ask what they recommended... answer is, for the moment, keeping the pressure a bit lower (80 psi instead of the 95-100 psi tyre max), and keeping an eye on it...
But they said something else too. As they were looking at the exploded tyre in detail a couple of days ago they found a little engraved inscription (black letters onto a black background, so completely invisible if you are not looking for it) saying : "Do not use with no hook rims..." So it appears that this would be the reason for the explosion, not a product fault. I said then that I was happy to pay for the tyre since this had nothing to do with the garantee, but they said it was OK... which confirms how good these people are, and I am happy they are my LBS!

Anyway, since I don't want to buy and install new rims on these wheels, I have 2 options:

• Anyone heard of tyres (27 X 1-1/4) compatible with rims with no hooks? (Putney cycle have nothing in their catalogue)
  
• If anyone has a set of 27 touring wheels, with good rims (not steel), good hubs, stainless steel spoke, in good condition and super cheap, please do not hesitate to pm me!!
  
  

Thanks
