No used ears.co.uk before so can't say if they're any good. all i know is that mytyres.co.uk is delticom and they ship from germany (here in <48hrs thou).
Personally I'd go for the Nokian zLine, or maybe the Hakka black, they also come in 225 40 18 but am sure the Pirelli is good too (got the Pirelli Cinturato P7 225/45/17 on my Mk7).
