I bought a tubeless wheel and tyre combo about a year back but never got round to fitting it. Dug it out of the shed and had a good look over it and the tyre isn't right on the bead at one side. It looks buckled under, so to speak.

I've tried deflating it and applying a load of tyre soap and then reinflating it while bouncing it to try and seat it. I've tried a ratchet strap round the outside. I've tried levers and more soap. Had it up to 70 psi but it still won't seat.

It holds air inflated but I'm not sure I'd be happy running it.

Any other tips or tricks that might get it seated right?

If it were mine,I'd soap the side of the tyre and inside of the rim,pump it up to 100psi and if it doesn't pop within a few minutes I'd leave it over night and see if that works.

Is it safe to go as high as that?

It sounds to me that the tyre's steel beading is knackered probably due to poor fitting procedure in the first place?
If this is the case you should scrap the tyre. It's not worth the risk.

I agree with this but you will need to break the bead all the way round and might then struggle to re-inflate with home based compressors.

Cheers, I did manage to get the tyre off the bead on the affected side but it always seems to stick somewhere round the rim - not always in the same place though. I'm starting to wonder if the tyre itself might be defective.

I've tried very liberal amounts of tyre soap all over the rim and tyre with no luck.

Personally, I'd take it to a tyre shop. Even though they may not be able to fit a tyre on a 10" rim, their air compressors are so much more powerful and they have great experience of all things rubber related

You definitely need to take your wheel to a tyre fitter & let them try to seat it for you, seeing as you've tried a lot of the good suggestions that usually work.
Inflating the tyre up to 100 psi is daft & bloody dangerous... Why on earth would you inflate a tyre to 3 times it's working pressure?? & then fit it to your bike go for a ride!! If you want to see what happens when a tyre fails when it's being inflated, check out YouTube. I've personally been in the same workshop when a faulty lorry tyre burst at not much more than 100psi...there's a lot of kinetic energy not to mention rubber & steel rope pieces!! plus a very real chance of being killed as happened to a fitter at one of our depot's.
Every tyre is marked with safety information for a reason...

"& then fit it to your bike go for a ride ".............where does it say that.

It says: 70psi which is still twice the rated pressure.
I tell thee that tyre's knackered.
