I use park tools plastic levers, hook one under, then about6 inches away hook the other one under... then lift both at the same time, the rest is history... and I have got some right buggers off!!!
Try the W U method!
Hope it works for you, nothing worse than getting stubborn tyres off, well I suppose there is but it's a bummer!
