I think probably all-season tyres are actually the way to go. Full winter tyres only really work properly below temperatures of 7 to 7.5-degrees Celsius and really there's only a few weeks when the mean temperature gets that low in Ireland.

 

If you live in a remote spot, especially in the Midlands or North East where the snow and ice tend to be worse, then yes, winter tyres from late October to late February are probably a good idea. For the rest of us, regular tyres (or possibly those all-season ones) and a bit more care and attention to how we drive are probably sufficient.
