Tyre bead seating problems - SOLVED

[Taught2BCauti...]

Recently fitted a new rear tyre, and all was well until I hit a pothole that was impossible to avoid, and suddenly lost all the air.

Fortunately, this happened very close to my regular local Tyre Fitter's, and I was able to push the bike there for them to have a look.

They found no damage to tyre or rim, and they were able to re-seat the tyre with their air-line, but when I got back home, it went again as I turned into the drive.

I checked and cleaned the rim and tyre, and gave it a smear of Fairy Liquid, and it re-seated again - but it's still leaking from all around the rim, but on one side only.

I'm guessing I need something better than Fairy Liquid to do the job properly, but what?

Has anyone else had this problem, and if so, what did you use to fix it?

Rather than a smear of fairy liquid, give it a good clagging of soap with an old paintbrush or a sluice round with watered down fairy liquid. Remove the valve core and bang the air into it as quick as you can until you hear the beads pop on. Then quickly screw the core back in.

Rinse off the excess soap with warm water to stop the rim spinning in the tyre.

No problem giving it an 80psi blast from my compressor with the valve core removed, but I have already tried Fairy Liquid and Swarfega, neat and diluted, but the tyre still goes down, in a sea of foam from the rim, in an hour or less.

I'm starting to think in terms of silicone sealant, roofing mastic, or something like that, but not sure what will fix it for good or make it worse.

Tyres seem to be getting harder to seat. I used to be able to seat BT010's/Diablo Stradas almost instantly without removing the valve core and using my 25 litre compressor. The PR3's I have on the TDM now my mechanic REALLY struggled with his huge compressor and the valve core removed. With one he had to use a ratchet strap to squeeze the tyre closer to the bead.

Older wheel may need bead sealer common on Titian scooters and some Honda's particularly the Italian built ones

Just tried again, the bubbles are very fine, and definitely coming from the joint between the tyre and the rim - all the way around apart from 2 x 5mm gaps.

Probably going to need an inner tube to fix this

Tire off, check bead and rim for damage. Clean up rim with a mild abrasive pad and... if it were not powder coated I would give a coat of paint.

A large tin of bead sealer is about 10 quid and would be a much better idea than tube.

What tyre is it?

It looks like a Mitas one from the font on the side?

A top tip for seating a bead:

1) Wrap a Ratchet Strap around the circumference (tread part) of the tyre.
2) Tighten the strap carefully as it can slip off if not aligned properly.
3) The compression of the tread will squeeze the bead out to the bead seat.
4) Once you have 360° contact blast a bit of air into it.
5) Release the strap before continuing the blow the tyre up.

This is how you get stubborn tyres to seat on the rims of Earth-movers.

More professional outfits use their truck mounted tyre handler pads to crush the tread and seat the bead. Same principle.

[Taught2BCauti...]

The powder coating inside the rim is clean and shiny, like factory fresh, and it does seem to be getting better with each attempt, and there are now 5 small areas with no bubbles.

The tyre is a Mitas (well spotted) and I can't see or feel anything out of the ordinary around the edge, and there are no leaks at all on the opposite side.

I have tried most of the suggestions, so thanks for that - but I've given up now and dropped the wheel off at the local tyre fitter, and they have promised it back for tomorrow.

Just picked the tyre up, and it is sorted.

They removed the tyre and cleaned-up the bead with wet and dry, then re-seated it with a product called 'FirmaPress' (or PermaPress?).

Bloke said; "Sometimes you get a tyre that just won't seat properly, and it's the only thing that works."

I tried for ages once to seat the bead on a Continental tyre. It would not budge. I blasted it with an air compressor up to 90psi, I was using neat fairy liquid, ratchet straps around the outside but no joy, I was on for hours doing it.

In the end I took it to a local tyre factors, and the lad there had a bucket with a soap mix, just plain soap he reckons mixed into a runny solution, he lathered it up the sidewalls and put 40psi into it and it snapped home instantly. Took him about 2 minutes.
