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?
