Rear tyre not seating on rim

[pintlicker]

Hi, on the way back from work the other night on my 1999 Fazer I picked up a puncture with a screw in the back tyre.  Ordered a new tyre from mytyres and fitted it yesterday, only took 15/20 minutes but I'm buggered if I can get the tyre to initially inflate on the rim.  I've triple checked the size, made sure the valve core is out, chucked on the lots of lube and tried a ratchet strap down the centre of the tyre but it's been incredibly stubborn.  I took it to a local garage to try to see if they could get it on but they had an issue as well but recommended finding somewhere that had a bead blaster thing.  I do remember the last time I put a new rear on it was a bit tricky to get a seal, but lots of lube and playing about with the tyre got it on. 

I'm going to try and find an open tyre place today but I don't suppose anyone has any other tricks that might help?

This is a last resort method and should be used with extreme caution and only when every other method has failed.

Take the valve core out.
TAKE THE TYRE AWAY FROM THE BIKE AND ANYTHING ELSE FLAMMABLE. <<< Most important!!!!!
Push a section of tyre off of the rim & squirt some brake cleaner or easy start into the gap.
Now carefully with a taper or a long cooker lighter ignite the brake cleaner.
There will be a loud bang and the tyre will be forced on to the bead.
The residue will probably burn off for a few seconds so either throw some water on it or slap it out with a damp rag.

More importantly if you set fire to your garage or lose your eyebrows then it's your own fault.

With the tyre off, check for any damage to the rim. It is possible also the the rim is out round or has a flat spot, a friend had similiar trouble and I took the wheel into where I work and using a dti clock found two large flat spots, he had to buy a used wheel in the end.
Where the bead sits get some emery cloth on it as well and lightly rub it down, this will remove small imperfections and also help to show up any dings or dents.

How do people find these things out???
It must be by accident? 


I bet there was a very relieved person sitting there looking at the result with no eyebrows and half a head of hair, smoking a Hamlet, and a big cheesy grin on his face.

The rim is clean and doesn't have any obvious dings.  I did see the brake cleaner method but I'm going to use that as a last resort!  Looks a bit hairy to me.


Did a bit of a tour around some car tyre places this morning and they couldn't get it inflated either, they didn't have a bead blaster and weren't really too interested in helping.  One guy seemed to think it hadn't been stored right and had become squashed a bit and the space between the rim and tyre was too much to get a seal.  He recommended bringing it into the house and sticking it by a radiator to warm up for a bit then walloping on loads of paste, the ratchet straps and giving that a go.  I'm out of lube  [/size][size=78%] [/size][/size]so it'll need to be tomorrow, although I think a local mechanic has one of those bead blaster things so might try to catch him in the morning.    Its never easy![size=78%]

I can remember seeing it from an early ae as a kid watching my godfather race, it was pretty much the normal method of beading tyres in the pits. First time i did it i nearly shat mysef, but it works

My dad and both of my brothers were all tyre fitters years ago but they never pointed that one out to me before.
Not exactly one for the Health & Safety brigade but yeah it certainly does the job on that evidence.

I must admit that when I typed it I was thinking that I am really gonna get slated by the H&S brigade on here for this.... Must say that I am surprised and I must try harder.

Had the same thing with last set, garage ended up putting an inner tube in rear to push out bead. Going back to have it taken back out when start riding again

I've fitted loads of FZS600 rears without a problem if you're near central southern England I'll help you out.

The mobile tyre fitter that put mine on had to do the same with an inner tube but took it out beforehand. I think he used it to push the bead out then put a ratchet strap on it.

Is it a Michelin PR3 or PR4 by any chance, a pain in the arse to seat. The 4 is even worse than the 3

I found that standing the wheel upright with the valve at the bottom (core out) and kneeling full weight on the tyre to push out the bead was the only way I could get them to inflate and pop.
Last one took 10 minutes to change and an foccing hour to inflate pop

[pintlicker]

Yes, funnily enough its a PR3.  Took it down yesterday morning to the guy with the bead blaster thing and, to be fair to him, he gave it 4 or 5 goes but couldn't get it to seat. 


Last night I took it off the rim and sat it next to the radiator for a couple of hours with a ratchet strap round the center and some things inside the tyre to push the bead out.  Worked a treat, put the tyre back on and ratchet strap round the tyre again and it inflated!  I'll balance and refit tonight, was nearly midnight when I got done and snowing all night last night so wouldn't have been able use it anyway today.  Was so overjoyed at getting the bugger up had to have a couple of beers to celebrate.

Good to hear you got it on!


As an aside to the seating it with fire thing (in case someone else wants to try it), make sure you have the compressor ready when you light em, i've had them slip back off the bead if you don't get the air into them before the air inside the tyre cools down and contracts (particularly PITA tyre that was).
Sometimes the wheel will jump 2 feet in the air when you do it, which is fun!  But i did hit myself in the hand once.  Not the face at least.
If it doesn't work the first time you have to wait a while before there is enough oxygen in the air inside the tyre for it to work again.


That's my experiences with it anyways .
