Guys - a good spot for tyres and worth checking out if you're in the market is Tallaght Tyres in Old Bawn. This is where I got the best price for my last set of tyres so I gave them a shout back.
They are cheaper than eire-tyres for the tyres I chose, i.e. 140EUR for Dunlop SP Sport 9000 and this includes fitting and balancing.
Not sure whether they do Toyos or Good Year but worth a phone call all the same
