Tube explosions..thoughts

i havent used this method with the contis, mainly because once i got the buggers on, if i took them off again and then tried to put them back on with the tube, i would definitely kill the tube or myself with frustration

Apart from some of the useful tips previously mentioned...

When you start finding it hard to mount the last section of bead (usually a 3-6" section around the valve) go back around the mounted portion of the tyre, pinching it together towards the centre of the rim. This seats it deeper in the rim, effectively reducing the circumference it's stretched around, and freeing up enough slack sidewall to get it over the final bit of rim.

And don't forget you can also rest your thumbs for a bit by turning the wheel around and using your fingers to scape it up and back towards you.

Photos would help I suppose.

Also,when you get to that last niggly bit it can help to empty the air out of tube.

How about a tyre changing demo? Hyde Park.. beer.. flyers.. bands.. winston's roll(er)s.. ;)

Don't put the tube in the tyre first. That's the aidan/muppet method ;)
Do put a small amount of air in before fitting as it makes it easier to fit onto the rim/into the tyre.
Fit one side of the tyre into the rim, ie. one of the beads into the rim wall, the other still loose, work slightly inflated tyre into this careful not to pinch it, work loose bead into rim wall.. push in a bit of tube.. push in a bit of tyre.. continue this until nearly done and then hold wheel into chest with loose side away from you. Then push wheel into chest and use thumb force to push final hard bit of tyre into rim.. watching to make sure no tube is poking out. Push valve in. Push tyre down over valve. Spin to check for bumps. Flawless.
I've never used talc.. well, maybe once.. knock yourselves out.
Do thumb exercises. Fitting brand new tyres is one way to do this.
HTFU
moo.

What type o wheels have you got out of interest? (clefty)

Avoid levering the tyre on at all costs - rub a little bit of washing up liquid all round the bead and even the tightest damn tyre in the world will go on so easily you wouldn't believe it. And if you've got a brake don't get a drop on the rim... you're brake will probably work but it'll make a right racket

asm What type o wheels have you got out of interest? (clefty)

they're the stock Alexrims dm18's i got with the bike, even with my little (read 'no') knowledge or wheels and rims i am realising that they are rather cheap...

but good news guys, with thumb and talc power alone, and several other tips picked up here (wasnt actually as bad as i thought it would be)
I now have a set of contis running at around 100-110 and they havent popped (yet) hurray!

there was some wary pumping going on when i got towards 100 mind ;-)

Here's a good video IMHO.http://www.youtube.com/watch?v=BmNo6rFKMzE

kowalski I've had nowt but trouble with Contis.

Because they're a bitch to fit, there's a good chance of damaging the tube when you do.

As RPM says, decent rim tape is a must. I've had a puncture cos the cheapo rubber band type failed. Conti tape is top, but I use Veloplugs which are toppermost.

Where did you get your Veloplugs™ from ?

Soweto888 . . . I even had a couple explode while I was inflating them. The noise in a confined space isnae real. I still get a bit jittery when I'm using the track pump...

I had a MTB tube explode on me while I was pumping it up with a track pump in my kitchen - no more than 65 psi - the volume was just incredible, my girlfriend who was in the kitchen at the time screamed and I nearly had a heart attack, both our ears rang for minutes afterwards.

That is the technique I have always used, push the bead towards the centre of the rim at the position opposite the valve - work your way around, tyre pops on, I have not come across a tyre that has not yeilded (and easily) to this method - although I am sure there may be wire beaded tyres out there that need a crow bar.

Yeah, it's horrible. I'd forgotten about the ringing ears, but I do remember that I was in the hallway: the walls can't be more than two-and-a-half feet apart, which just made the experience all the worse. It's not something you forget in a rush. I mean, I'm not going to claim that I'm awake at this ridiculous hour because of the one that popped when I was tucked up in bed - it's not like I haven't slept since June or anything. However, I'm really am quite twitchy around the track pump now. I stretch the tubing out to put as much distance between me and the tyre as possible. Maybe I could get one with a really, really long air hose - inflate my tyres from another room.

Get your self a pair of ear plugs from Boots™ - you will probably blow another couple of tubes over the next few years, and as you know when these things blow they really kick out some sound, especially indoors. It takes the fear out of perforating your eardrums.

Use a pair of boots ear plugs like the ones above, I stick these in and put on my angle grinder ear defenders on !!! - once you have been stung by a complete tube failure at high pressure with your head 2 foot away you do not forget it !!

Cue: someone post the 'harden the fuck up' video :)

I have only once had a tyre explode outdoors (glass shard) the sound was not as biblical as indoors but still had everyone within 500 yards looking around for the man spreading the word of god.

Well, yeah, I did feel a bit girlie as I was typing that out. Still, anyone wanting to point the finger and laugh should be prepared to lock themselves in a cupboard with a track pump and pop a tube at 100 psi.

Ben's Cycle in Milwaukie, they have a store on the bay and a website.

I hear you can find them at 53x12, a UK based store.

Yeh, sounds like a gunshot i know. Makes me jittery going up to 100psi too, but i'm more worried about the rim cracking and flying off into my leg at 500mph.

The worst i've had was setting fire to shotgun primers.. It looked like the fire had gone out.. I walked over and bent down to have a closer look.. Breeze picks up.. Flame appears.. Bang!!!

Reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee go my ears

fscking hell!!!! Don't play with explody stuff kiddies.

yup a friend of mine was at the local park riding a bmx, he hit the coping on a ramp and the wheel shifted. He bent down to adjust the brake pads so he could keep riding and it just blew up on his face! I've seen many other wheels blow up outdoors, but that guy was almost knocked over by the sound pressure!

When mine went it was sitting in the hallway and I had been in bed for about half an hour asleep, I thought someone was trying to break into my flat and jumped out of bed and grabbed the first weapon like object to hand..which actually turned out to be a coat hanger...a plastic one at that..

Where did your username come from then? Just wondered, cos it's my son's name :)

The tube in first method worked out ok, the tyre's still on the rim, it goes round, all is good. It was Bontrager's suggested method, although I'll try out hippy's next time

Rims definitely make a difference to how easy it is. Tyres are much easier to put on my CXP33 than my CXP22.

It is my middle name, I am about to deliver Evans a new customer around March (well not me of course but my girlfriend) - and we are thinking about 'Tynan' as a name !!!!

I thought I was the only one !
