Fitting tyres

Any voodoo tips for a person who can’t get a tyre to seat properly? Please don’t say fairy liquid...
I’ve sanded down the inside of the rim to rid it of rust, the tyre still isn’t opening up and seating properly. The inner edge is staying ‘tucked into’ the rim inner. Do I need to use grease?! Or is there a non detergent solution?

@spookdog just recently done both tyres on my husky and both had this issue and it seated normally after I inflated the tyre just keep inflating until you see it seat and leave it a while to settle then loose it down to your preferred PSI
@declan
Cheers bud, I’ve only ever had this problem once before. That was a heavy duty alloy of a Suzuki. It took stupid psi to pop the bead into place.
I’m just wary of putting my crusty rim under that kinda pressure, don’t know why though, I’ve had push bike tyres that are 40-60 psi iirc... -

Take the valve core out if you are going to inflate to silly psi so that you can let it back down again quickly

I used to have this problem fairly often with Avon TrailRiders in the recommended sizes on DTR rims; excellent tyres but it was always difficult to get them to pop the bead and sometimes I had to deflate the tyre completely, remove it and refit 90 degrees around the rim. This is even after blowing them up to 50psi with the valve core removed using a compressor. I've had to leave them at this pressure for 30 minutes or so in the past as well, and resort to other tricks like hammering the sidewall kind of downwards with a rubber mallet at the affected spot (watch the rim!). It was only ever a problem with this particular make and model of tyre, they were ace on the road but Avons have always been a bit strange.
Most bike shops fit tyres using the 50psi-no-valve-core-compressor method. This might not be what you want to hear but if your rim responds to this treatment by exploding then it was a pretty safe bet it was sufficiently corroded to be unsafe to use. Slightly off topic but there's a well-known story called "The Imprint of Death" they tell kids at tech colleges about a tyre fitter who was fitting a truck tyre and didn't bother using the circus animal-sized cage they put them in to pop the bead; it went bang and half of him ended up stuck to the ceiling. A bike tyre won't do that but still has a lot of energy stored in it, enough to do someone serious harm if they're stood right next to it. I think if I was worried whether a crusty rim of mine could handle 50psi, I'd be on the lookout for a new wheel to be honest.
