I can not get tires to stay on my Weinmann rims

piss off.

I can see its a clincher rim. Ive got loads of old bikes more without hooked rims than with.

no offence intended mate..

I can't believe that this guy is basically being avised to basically "glue some tubs on" to his rim tape :))

You need a steel beaded clincher tyre ( they don't flex so much as the folding kevlar beaded modern types apparently).

And they rims are only rated up to 100psi max.

Get a nice old pair of michellin dynamics from chain reaction for about £18 a pair.

I run this combo with no problems after having a gatorskin blow off whilst standing still (at about 120psi.)

nice dude, thanks, what width? 700x25,28,32?

I was right, woop!
umm I'd say go for 28, but only cos i don't know the inner diameter of your rim.
measure that and that will help a bit.

16.56mm near the bottom and 18.54 near the rim, digital calipers... boo yeah... i hate my life of model making.

fred!!!

Me and you.....outside......nar!!!!!

;)

I never mind being corrected though, as my thoughts are often wrong.

In my defense, I DID qualify my statements.

Someone else may tell you differently, and more correctly, but those rims are not for modern clincher tyres.

I'm guessing that the rim is of a rather old design, and may have been for large diameter touring type tyres. But its a guess...

Digital is crap. Film FTW.

So there.

that's a rim from a mid-80s Gregham agricultural seed hopper, mkII. You'll need a set of these:

these type of older rims were the norm but generally phased out in the late 70's in favour of the narrower hooked modern rims, older style touring tyres were fine on them if inflated between 60/80 psi (if you had a need for lighter rims you bought sprints and tubs) most modern tyres especially folding warn not to use on this type of earlier non hooked rim.....most bike shops should be able to source you a decent 700/28 tyre that would fit ok though

Thanks everyone, definitely helped out, I went with these:

they should last me until i can grab a set of "modern, non agricultural speed hopper mk II form the mid '80s rims" if anyone knows anyone dumping a set of 700s let me know, cheers again

I'm running 700x25 with no probs.

One very good trick to help your tyres stay on the rims is to use two rim tapes - this makes it much more difficult for the bead of the tyre to sink into the well of the rim at one place which then allows another part of the tyre to pop off the rim. You can also build up the thickness of your existing rim tape with insulation tape. This trick works time and time again and was the only way to get the tyres to stay on the rims of my Kingcycle when the tyres were inflated to 90psi...

those rims i was on about are now for sale if anyone wants them....

hey - what happened and how much are you looking for for the set or is it just the rims?

Huge, i will fill you in, after i get back from work not ignoring you dont worry hahaha and its a full wheel set, and one tire.

so those wheels, I just decided to go with smaller rims at higher pressure for a more uncomfortable ride.... anywho, if you are interested in the wheels let me know, I will clean them up a bit, but the rims are Weinmann 700C-17 x 622 and the hubs are Maillard, the rear has 83 stamped into it. If you need more pics let me know and i will get back to you with a price

Hey - some more photos and a price would be good.

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

Ideally, I would prefer to find suitable tyres and keep the wheels, as they are original...

Any idea? Don't let me put 700c on that beauty...

Thanks

My apologies, I had not read the thread till the end, maybe I stopped reading when it was about gluing tubs on clincher rims, Haha (no offense guys!)...
Anyway, as I did not read till the end, I missed these two precious posts...

So exploding gatorskin on hookless gatorskins is not something new... When the tyre exploded it was infated at 95-100 (I know for sure because when I took the bike that morning, it had been sleeping in the shed for a while and I inflated front and back... After explosion I took instinctly some pressure off the rear tyre, that was a good idea then... I am now using the bike with the same "unappropriate" gatorskin, at 80 psi... I might try Hilary's trick of adding more rim tape, this is genious...

If anyone is interested in a pair of gatorskin, 27, for their wheels (with hooks), maybe we could find a deal... I would then go for Spuds recommendation ("good old michelins", or similar "Rigid" tyres...
