For the likes of yourself who's not going to be worrying about the rain every day something like Bridgestone Potenza RE070 would be a good shout. They're only available in 225 or 235 width but the 225 is close enough to be within tolerance. I run them over here during our summer and they are a great tyre.
A quick check shows that the Bridgestone is around £6 per tyre cheaper, well over here anyway.
