Seating tyres

Ok so, I spent twenty five minutes today trying to get a tyre to sit properly on the rim. I tried a load of washing up liquid and soapy water but just couldn't get the damn thing to sit properly.

I must have had the tyres up to 100 psi but the damn things were not budging they just wouldn't pop.

By the way they are tubeless tyres but I was using tubes. I have had this problem before with these tyres they are super tight but tonight I just gave up.

So what is the trick? Has anyone ever tried soaking the tyres in boiling water for a while prior to fitting?

a little bit of muc off between the rim/tire and one of these

The muc off i can manage but that other fancy yoke? I might just try the coal tongs and a bit of rope
